The rate of a gas phase reaction is given by K . CA . CB. If the volume of the reaction vessel is reduced to l/4th of its initial volume, then the reaction rate compared to the original rate will be _______________ times?
Correct answer: B. 16
- A. 4
- B. 16
- C. 8
- D. 2
Explanation
With the same reactant amounts and temperature, reducing the volume to one-fourth makes both concentrations four times larger. Since the rate is proportional to CA CB, it increases by 4 × 4 = 16 times.
