For the reaction : 2N(2)O(5)rarr4NO(g)+O...

For the reaction : `2N_(2)O_(5)rarr4NO_(g)+O_(2)(g)` if the concentration of `NO_(2)` increases by `5.2xx10^(-3)M` in 100 sec, then the rate of reaction is :

A

`1.3 xx 10^(-5) ms^(-1)`

B

`5 xx 10^(-4) ms^(-1)`

C

`7.6 xx 10^(-4) ms^(-1)`

D

`2 xx 10^(-3) ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
a
`2N_(2)O_(5(g)) to 4NO_(2 (g)) + O_(2(g))`
Rate of reaction with respect to `NO_(2)`
`=(1)/(4) (d[NO_(2)])/(dt) = (1)/(4) xx (5.2 xx 10^(-3))/(100) = 1.3 xx 10^(-5) ms^(-1)`.
