Mass Action Exercises:

Write the rate law for the following reactions based on mass action.

Remember, the law of mass action states that the speed (rate) of the reaction is proportional to the concentration of the reactants/ substratea. This proportionality is most often a product of a rate constant (k) times (*) the concentration of the substrate (S).

1.) A ->B

2.) A+B->AB

3.) A+B->C

4.) C->A+B

5.) A+B+C->ABC
