The reaction A + 2B $\rarr$ products was found to have the rate law;
rate = k[A] [B]². While holding the concentration of A constant, the concentration of B was increased from 0.010M to 0.030M. Predict by what factor the rate of reaction will increase.

Question

The reaction A + 2B

\rarr

products was found to have the rate law;
rate = k[A] [B]². While holding the concentration of A constant, the concentration of B was increased from 0.010M to 0.030M. Predict by what factor the rate of reaction will increase.

Quizplus · Accepted Answer

The rate law indicates that the rate is proportional to the square of the concentration of B. Increasing [B] from 0.010M to 0.030M is a threefold increase, and since the rate is proportional to [B]^2, the rate increases by a factor of 3^2 = 9.
