Question

The following is a multi-step reaction. The rate-limiting step is unimolecular, with A as the sole reactant.

Please provide the three steps and highlight the specific answers for each M/s

The following is a multi-step reaction. The rate step is unimolecular, with A as the sole reactant. C+ D A B If [A] and [B] are both 0.170 M, then the rate of reaction is 0.0020 M/s. (a) What is the rate of the reaction if[A] is doubled? Number 0.01 (b) Starting with the original concentrations, what is the rate of the reaction if [Bl is halved? Number MI s 0.005 GD Starting with the original concentrations, what is the rate of the reaction if [A] and [B] are both increased by a factor three? Number

Explanation / Answer

since rate limiting step has only A and that too is unimolecular
rate = k [A]

a)
if [A] is doubled, rate will also double
rate = 0.0020*2 M/s = 0.0040 M/s
Answer: 0.0040 M/s

b)
since rate is independent of concentration of B, rate will not change
Answer: 0.0020 M/s

c)
[B] will have no effect
since [A] is tripled, rate will also triple
rate = 0.0020*3 M/s = 0.0060 M/s
Answer: 0.0060 M/s
