Question About the 1st Order REaction Rate Law

Postby Rhiannon Imbeah 2I » Thu Feb 23, 2017 1:41 am

Will we ever have to use this rate law to calculate the product concentration or is it only used for reactant concentrations?

I think you're talking about the differential rate laws because for the first order rate law, you just have to work with initial and final concentration, one of which is usually given to you. But for the differential rate laws, which I think the question is referring to, then yes you have to always use reactant concentrations.

I think that reactant concentrations will always be used unless the reverse reaction is used! (so technically the products are now the reactants)
