For the reaction
` 2N_2O_5 (g) to 4NO_2 (g)+ O_2(g)`
If the concentration of ` NO_2` increases by ` 5.2 xx 10 ^(-3)` M in 100 s then the rate of the reactions is :

A

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

B

` 0.5 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
Rate of reactions = ` (1)/(4) (d(NO_2))/(dt) = (5.2 xx 10^(-3))/(4 xx 100) `
`= 1.3 xx 10^(-5) Ms^(-1)`
