Part A: Law of Mass Action 10 points

 

In the reaction: A + B ------> C + D ; assuming the reaction is first order with respect to both the reactants A and B;

the rate expression is: Rate = k[A][B]. The reverse reaction is not a factor in the initial concentration changes.

Demonstrate the Law of Mass Action in explaining why you multiple the concentrations A times the concentration of B in the rate expression

( [A][B] ) .
