The reaction A + 2B $\rarr$ products has been found to have the rate law, rate = k[A] [B]². While holding the concentration of A constant, the concentration of B is increased from x to 3x. Predict by what factor the rate of reaction increases.

Question

Quizplus · Accepted Answer

Given the rate law is rate = k[A][B]^2, when the concentration of B is tripled (from x to 3x), the rate increases by a factor of (3x)^2 = 9x^2 compared to the original x^2, thus the rate increases by a factor of 9.
