The rate of gaseous reaction is given by the expression k[A]2[B]3k\lbrack A\rbrack^{2}\lbrack B\rbrack^{3}. The volume of the reaction vessel is reduced to one half of the initial volume. What will be the reaction rate as compared to the original rate a?

A

18a\frac{1}{8}a

B

12a\frac{1}{2}a

C

2a2a

D

32a32a

Answer

32a32a

Explanation

Solution

Rate =k[A]2[B]3=a= k\lbrack A\rbrack^{2}\lbrack B\rbrack^{3} = a

When volume is reduced to one half then conc. Of reactant will be doubled.

Rate =k[2A]2[2B]3=32k[A]2[B]3=32a= k\lbrack 2A\rbrack^{2}\lbrack 2B\rbrack^{3} = 32k\lbrack A\rbrack^{2}\lbrack B\rbrack^{3} = 32a
