The rate constant for the reaction, 2N(...

The rate constant for the reaction, `2N_(2)O_(5) to 4NO_(2) + O_(2)` is `2 xx 10^(-5) s^(-1)`. If rate of reaction is `1.4 xx 10^(-5) mol L^(-1), s^(-1)` What will be the concentration of `N_(2)O_(5)` in mol `L^(-1)`?

A

`1.4`

B

`1.2`

C

`0.04`

D

3

Text Solution

Verified by Experts

The correct Answer is:
D
As per units of rate constant, it follows first order kinetics w.r.t. `N_(2)O_(5)`
`[N_(2)O_(5)]=("rate")/(k) =(3.90xx10^(-5))/(1.3xx10^(-5))/(1.3xx10^(-5))=3M`
