Your voice is so calm, I wish my parents spoke like this.

Stop disappointing them for once and maybe it will change

Thank you for explaining this. Your voice is also very pleasant to listen to. Keep doing great work.

how did you get 3/2???

[@resilientlemon1302]

For Example 2 should you not have divided the equation by -1/3 instead of 1/3?

[@lindsayk616]

The negative is only there in front of the 1/3 to make the rate positive for the reactant, since the reactant is disappearing. If you didn't have the negative there, you'd end up with a negative rate for the reactant, since in your numerator you'd be subtracting a larger number from a smaller one (b/c the concentration of the reactants decreases over time, so concentration2 will be less than concentration1, and change in concentration is defined as concentration2 - concentration1) You don't have that issue with products; their numerators will be positive values since they increase in concentration. Thus you only need to divide by 1/3. I hope that made sense.

@@lindsayk616 hey. So it’s basically there for that and the sign is always excluded in calculations?

Thanks Soo much for that explanation, please for more examples

Please make more videos for gen chem 2 :) ex. kinetics, more rate law videos, equilibrium

[@boomfiziks]

Wow! That was helpful! Thank you. I was getting hung up on lumping the fractions with the initial rates and why my problems were not working out correctly. Plus, the last part of using stoichiometry gave me a nice alternative and a means to check my work. Thank you again!

You're really a genius, I can solve rate reaction in a second. Thanks so much for helping me on this tutorial 🙏🙏

Thank you for explaining this in a way that I could understand :)

[@JessicaCaldwell-n4u]

What happened to the negative on the 1/3? Should it be -3/2?

[@MohaleNdlovu]

Wht about the negative sign of reactant do you include or not include in calculationb of disappearence of H2

Isnt the rate of disappearance should be negative? Since it’s in the reactant side?

[@resilientlemon1302]

Yeah that's what I was thinking

[@linsdesk7240]

@@resilientlemon1302 - hi! Update: yes, it has to be negative since it is in the reactant side. We had a test last week and Inwas correct.

[@ntnjadeabdulhadi3386]

you forgot the negative sign or (minus) on the final result because whenever the product appear+ the reactant disappear -

[@nickc4336]

You would be technically correct, but It's usually customary to always write reaction rates as positive. The appearance or disappearance of a reactant or product is differentiated using the phrases "rate of appearance" or "rate of disappearance", or simply checking if the chemical in question is a reactant or product.
