For the multi‑step reaction A + B ⟶ C + D the rate‑limiting step is unimolecular, with A as the sole reactant. If [ A ] and [ B ] are both 0.145 M, then the rate of reaction is 0.0040 M / s. What is the rate of the reaction if [ A ] is doubled? rate: .00799 M / s Starting with the original concentrations, what is the rate of the reaction if [ B ] is halved? rate: .00200 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 5 ? rate:
