Question
The reaction 2A + B → products was found to have the rate law, rate = k[A][B]. Predict by what factor the rate of reaction will increase when the concentration of A is tripled and the concentration of B is doubled.
Correct Answer
Option C is the correct answer.
Detailed Explanation
Initial rate = k[A][B]. New rate = k[3A][2B] = k × 3 × 2 × [A][B] = 6 × k[A][B]. The rate increases by a factor of 6.
Hint
Multiply the factors for each concentration: factor for A is 3, for B is 2.
