The rate law for the reaction, A + B → P is rate = k [ A ] [ B ] . The rate constant of the reaction is 4.5 M − 1 s − 1 at 2 5 ∘ C. Calculate the rate of the reaction when [ A ] = 0.1 M and [ B ] = 0.

Question

The rate law for the reaction, A + B → P is rate = k [ A ] [ B ] . The rate constant of the reaction is 4.5 M − 1 s − 1 at 2 5 ∘ C. Calculate the rate of the reaction when [ A ] = 0.1 M and [ B ] = 0.2 M.
