Two reactions proceed at same rate at 25...

Two reactions proceed at same rate at `25^(@)C`. The temperature coefficient for the first reaction is 2 and that ofsecond is 3. The ratio of the rates of these reactions at `55^(@)`C is

A

`2/3`

B

`4/9`

C

`8/27`

D

`1/9`

Text Solution

Verified by Experts

The correct Answer is:
C
`r" "2^(1)r" "2^(2)r" "2^(3)r`
`r" "3^(1)r" "3^(2)r" "3^(3)r`
ratio of rates `=(2^(3)r)/(3^(3)r)=8/27`
