The rate of a gaseous reaction is given by the expression k[A][B] . If the volume of the reaction vessel is suddenly reduced to 1 / 4 th of the initial volume, the reaction rate relating to original rate will be :

Options

  1. A1 10
  2. B1 8
  3. C8
  4. D16

Correct answer

D. 16

Step-by-step solution

On reducing the volume 1 4 th of the initial volume, each concentration will be increased by 4 times. aligned ( Rate )₁ & =k[A][B] ( Rate )₂ & =k[4[ ~A ][4[ ~B ]] aligned Hence, [ Rate ]₂ [ Rate ] =4 4=16
