The rate of a gaseous reaction is given by K [ A ] [ B ] . If the volume of the reaction vessel is reduced to 1 4 of the initial volume, the reaction rate relative to the original rate is -

Options

  1. A1 16 times
  2. B1 8 times
  3. C8 times
  4. D16 times

Correct answer

D. 16 times

Step-by-step solution

Rate, r = K [ A ] [ B ] According to the given data, the volume of the reaction vessel is reduced to 1 4 t h. Hence, it can be written as r 1 = K [ 4 A ] [ 4 B ] = 16 K [ A ] [ B ] = 16 r ∴ r 1 = 16 r
