Which of the answer choices correctly defines reaction rate?
the amount of reactants used in a specific type of reaction
the amount of products produced in a specific type of reaction
the speed at which reactants change to products over a given time
the speed at which products decompose into reactants over a given time

you know its not a or b because "rate" implies speed, not amount. And you know its not d because products do not decompose into anything, they're already the end goal. So the answer must be C. Reaction rate is the speed at which a chemical reaction proceeds.
