A Level Chemistry "The Effect of Catalysts on the Rate of Reaction".

You can find all my A Level Chemistry videos fully indexed at www.freescienc...
In this video, we look at the effect of catalysts on the rate of reaction. First we explore what is meant by the transition state. We then explore how catalysts increase the rate of reaction in terms of activation energy. Finally, we look at the economic and environmental benefits of using catalysts.

Hi sir, you have just come up on my recommendation and omg the memories. i was watching 4 years ago. you really have helped me excel in my GCSE biology, chem and physics getting straight A’s whilst my teachers thought i’d fail. your videos are the best and so informative. years later i just wanted to say thank you and keep up the good work you’re changing lives honestly.

Thank you for your comment and congratulations on your GCSE results (even four years later). I'm glad I could help.

Greatest video ever made

Love your work, you helped me get an 8/8 in GCSE Combined Science when I was at a predicted grade of a 3/4, do you intend to do a video series on A Level Physics?

Sir do you know if we are getting every equation given to us for physics in this years GCSEs?

[@KaFullah]

Yes we are
