### Outline 6 Learning Objective

How do you show the rate of change of one species in a reaction is related to another species?

I think this has to do with the unique rate and the differential rate law. Remember that the rate of change of reactants and products relative to each other depends on their stoichiometric coefficients. For example in the reaction $2A\rightarrow B$, the reactant A is used up twice as fast as the product B is produced. The unique rate of the reaction equals $-\frac{1}{2}\frac{d[A]}{dt} = \frac{1}{1}\frac{d[B]}{dt}$. The rate that B is produced is 1/2 times the rate that A is consumed.

This learning objective relates to the homework questions 7A.1 and 7A.3. You need to look at the overall stoichiometric coefficients of the equation.
