The Arrehenius equation for the rate constant of decompoistion of methyl nitrite and ethyl nitrite are
`k_(1) (s^(-1)) =10^(13) exp ((-152300 J mol^(-1))/(RT))`
and `k_(2)(s^(-1)) = 10^(14)exp((-157700 J mol^(-1))/(RT))` respectively. Find the temperature at which the rate constant are equal.

A

`650 K`

C

`325 K`

D

`425 K`

Text Solution

Verified by Experts

The correct Answer is:
B

`10^(13)e^(-(Ea_(1))/(RT)) = 10^(14)e^(-(Ea_(2))/(RT)`
`T = 230K`
