Question
The reaction A + 2B → products was found to follow 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 D is the correct answer.
Detailed Explanation
Initial rate = k[A][B]². New rate = k[2A][2B]² = k × 2 × 4 × [A][B]² = 8 × k[A][B]². Factor = 8.
Hint
The factor for A is 2, for B² is 2² = 4; overall factor = 2 × 4 = 8.
