The following is a multi-step reaction. The rate-limiting step is unimolecular, with A as the sole reactant. A + B -----> C + D If [A] and [B] are both 0.170 M, then the rate of reaction is 0.0050 M/s. (a) What is the rate of the reaction if [A] is doubled? (b) Starting with the original concentrations, what is the rate of the reaction if [B] is doubled? (c) Starting with the original concentrations, what is the rate of the reaction if [A] and [B] are both increased by a factor of six?
