The decompostion of N(2)O into N(2) and ...

The decompostion of `N_(2)O` into `N_(2)` and `O_(2)` in presence of Argon follows first order kinetics `k=5.0xx10^(11)e^(-2000//T(K))`. The activation energy is

A

`16.628kJ"mol"^(-1)`

B

`166.28kJ"mol"^(-1)`

C

`166.28J"mol"^(-1)`

D

`16.628J"mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K=(5xx10^(11)).e^((-200)/T),K=A.e^((-Ea)/(RT)),(-2000)/T=(-Ea)/(RT)`
`epsilon_(a)=2000xxR=20000xx8.3.4=16.628,epsilon_(a)=16.628`KJ/mole
