Kinetics: Initial Rates and Integrated Rate Laws

[@ProfessorDaveExplains]

Hey everyone, KZbin is deleting annotations, and there is an error at 5:41 that I had fixed with an annotation so unfortunately I must simply list the correction here! The values at the bottom right should read: 0.04 = k(0.01)(0.250) and k = 16/(M^2 * s), when making the video I forgot to square [NO] so please make that correction in your minds, sorry about that!

2:30 When the concentration is doubled and the rate then also doubles, the reaction is first order with respect to that reactant. When the concentration is doubled and the rate quadruples as a result, the reaction is second order with respect to that reactant. If changes in the concentration doesn't affect the rate, the reaction is zero order with respect to that reactant.

In the realm of academia, where complexity often obscures understanding, the illumination of knowledge is a beacon of hope. It is with profound gratitude that I extend my appreciation to the creator of the invaluable tutorial video elucidating the intricacies of rate laws. This heartfelt ode seeks to articulate the depth of my appreciation for the educational oasis they have crafted amidst the arid landscape of academic challenges. The journey of learning is often fraught with obstacles, and the domain of chemical kinetics is no exception. With its labyrinthine equations and abstract concepts, mastering rate laws can be akin to navigating a treacherous sea. Yet, thanks to the altruistic efforts of educators like the creator of this tutorial video, this voyage becomes less daunting, and the shores of comprehension draw nearer. The video's inception marks a pivotal moment in the quest for understanding. Its existence signifies more than mere pixels on a screen; it embodies the convergence of knowledge and generosity, serving as a testament to the transformative power of education. Through meticulous explanation and illustrative examples, the creator has bestowed upon us a gift-a beacon of clarity illuminating the path to mastery. Every frame of the tutorial video is imbued with intentionality, each word a stepping stone towards enlightenment. It is evident that the creator's dedication transcends the bounds of obligation; it is a labor of love, fueled by a passion for fostering intellectual growth and empowering learners to conquer the formidable terrain of chemical kinetics. Beyond the confines of the digital realm, the impact of this tutorial video reverberates through classrooms and lecture halls, enriching the educational landscape with its profundity. As students, we stand on the shoulders of giants, leveraging the wisdom imparted by educators to scale the peaks of academic achievement. The creator's contribution, therefore, extends far beyond the confines of their video-it is a catalyst for intellectual evolution and a cornerstone of scholarly excellence. In a world besieged by uncertainty, the constancy of knowledge serves as an anchor, grounding us in the pursuit of truth. The tutorial video stands as a bastion of stability amidst the tumultuous seas of academia, offering solace to weary learners and guidance to those adrift in a sea of confusion. To the creator of this tutorial video, I extend my sincerest gratitude. Your dedication to the dissemination of knowledge is a testament to the transformative power of education. Through your selfless efforts, you have ignited a flame of curiosity in the hearts of learners, illuminating the path to understanding and inspiring generations to come. As the curtain falls on this humble ode, let us reflect on the profound impact of educational altruism. In the creator's act of generosity, we find hope for a brighter future-a future where the pursuit of knowledge knows no bounds, and the flames of curiosity burn eternal. To them, we owe a debt of gratitude-a debt that can only be repaid through the pursuit of knowledge and the dissemination of wisdom. In conclusion, let us cherish the creators of educational content, for they are the unsung heroes of academia-the architects of enlightenment and the stewards of knowledge. In their tireless pursuit of educational excellence, they inspire us to reach greater heights and strive for a future where ignorance is but a distant memory.

[@cyen923]

Elaphe Gutatta ehh not always true. Have you guys ever heard of repetition and familiarity? I know you have. Because I think learning really comes down to that. If we watched this youtube video before lecture, im sure the lecture would have made more sense versus when you watched a youtube video about that same topic. Now this does not mean there aren’t bad professors out there because there are...but I think one reason why you get a topic more after this video is because its PROBABLY your second time hearing about it. I think all we need is to learn a topic from DIFFERENT resources to actually understand or be ‘’more familiar” with anything... Thats what books, teaching assistants, tutors, youtube videos, khan academy!, homework assignments, worksheets, online simulations, etc., are for !😄

To find the order, instead of remembering what Dave said, simply write down the rate law for various trials and divide the ones with same concentration of either reactant. The rate constants will cancel out and you'll have a sweet equation which can ne solved to get the value of the order of the reaction!

[@robertmiranda2709]

@Majed Take the quotient of 2 concentrations of ClO2 and divide it by the quotient of the 2 rates, since the concentration quadruples and so does the rate 4/4=1

[@someaussiekidd]

@Majed because he didnt double the concentration, and then get quadruple rate, he QUADRUPLED concentration THEN got QUADRUPLE the rate. Its equivalent to doubling the concentration and getting double the rate which is FIRST order. (:
