For the multi‑step reaction A + B ⟶ C + D A+B⟶C+D the rate‑limiting step is unimolecular, with A A as the sole reactant. If [ A ] [A] and [ B ] [B] are both 0.125 M, 0.125 M, then the rate of reaction is 0.0070 M / s. 0.0070 M/s. What is the rate of the reaction if [ A ] [A] is doubled? rate: M / s M/s Starting with the original concentrations, what is the rate of the reaction if [ B ] [B] is halved? rate: M / s M/s Starting with the original concentrations, what is the rate of the reaction if [ A ] [A] and [ B ] [B] are both increased by a factor of 6 ? 6? rate:
