Question

In the given reaction:
A + 3B - C,concentration of A remain same and B
become double.Then rate of reaction would become
(1) 4 times
(2) 8 times
(3) 9 times
(4) 27 times.​

Answer 1

The expression for the rate of the reaction is

When the concentration of A is doubled, the rate increases 4 times.

Dividing (2) by (1), we get

When the concentration of A is tripled, the rate increases 9 Times

Dividing (3) by (1), we get=n2
