Question

For the reaction, \[\ce{A +2B → AB2}\], the order w.r.t. reactant A is 2 and w.r.t. reactant B. What will be change in rate of reaction if the concentration of A is doubled and B is halved?

Options

  • Increases four times

  • Decreases four times

  • Increases two times

  • No change

Solution

Increases four times

Explanation:

Rate = [A]2

If [A] is doubled then Rate = [2A]2 = 4[A]2 = 4 Rate
