the rate limiting step is unimolecular with A as the sole reactant.

A+B-----C+D
If A and B are both 0.200M, then the rate reaction is 0.0050M/s

A. What is the rate of the reaction if A is doubled?

B. starting with original concentrations what is the rate reaction id B is halved?

C. Starting with original concentration what is the rate reaction if A and B are both increased by a factor of six?
