Question Detail
Question
The reaction A + 2B → products was found to have the rate law, rate = k[A] [B]². Predict by what factor the rate of reaction will increase when the concentration of A is doubled and the concentration of B is also doubled.
Correct Answer
Option A is the correct answer.
Detailed Explanation
Rate = k[A][B]². New rate = k[2A][2B]² = k × 2[A] × 4[B]² = 8 × k[A][B]². The rate increases by a factor of 8.
Hint
Apply the changes to each concentration in the rate law separately and multiply the factors.
