Question

The following is a multi-step reaction The rate-limiting step is unimolecular, with A as the sole reactant. A+B rightarrow C+D If [A] and [B] are both 0.105 M, then the rate of reaction is 0.0080 M/s. What is the rate of the reaction if [A] is doubled? Number M/s Starting with the original concentrations, what is the rate of the reaction if [B] is halved? Number M/s Starting with the original concentrations, what is the rate of the reaction if [A] and [B] are both increased by a factor of five? Number M/s

Explanation / Answer

r = k [A]1 [B]o

a) 0.016 M/s

b) 0.0080 M/s

c) 0.04 M/s
