Question

For reaction $2A + B \rightarrow$ products, the active mass of B is kept constant and that of A is doubled. The rate of reaction will then.

• A. Increase 2 times
• B. Increase 4 times
• C. Decrease 2 times
• D. Decrease 4 times

Answer 1

Answer: (B)

Increase 4 times

Answer 2

Rate = $K(A)^{2}(B)^{1}$ on doubling the active mass of A the rate of reaction increase 4 times.
