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

`1.3xx10^(-5)" M s"^(-1)`

B

`0.5xx10^(-4)" M s"^(-1)`

C

`7.6xx10^(-4)" M s"^(-1)`

D

`2xx10^(-4)" M s"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Rate of reaction `=(1)/(2) (-Delta [N_(2)O_(5)])/(Delta t) =(1)/(4) (Delta [NO_(2)])/(Delta t) =(1)/(4) xx (5.2xx10^(-3))/(100) =1.3xx10^(-5)` M/sec.
