Question

For reaction $2A+B\to$ 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

The correct option is B Increase 4 times

Rate $=K\left[A{]}^2\right[B{]}^1$ on doubling the active mass of $A$ the rate of reaction increases $4$ times.
