The reaction
`N_(2)O_(5)` (in `C Cl_(4)` solution) `rarr 2NO_(2)` (solution) `+(1)/(2) O_(2)(g)` is of first order in `N_(2)O_(5)` with rate constant `6.2 xx 10^(-1) s^(-1)`. What is the value of rate of reaction when `[N_(2)O_(5)] = 1.25` mole ?

A

`7.75 xx 10^(-1) "mole"^(-1)s^(-1)`

B

`6.35 xx 10^(-3) "mole"^(-1)s^(-1)`

C

`5.15 xx 10^(-5) "mole"^(-1)s^(-1)`

D

`3.85 xx 10-1 "mole"^(-1)s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
Rate `= K(N_(2)O_(5)) = 6.2 xx 10^(-1) xx 1.25`
`= 7.75 xx 10^(-1) mol^(-1) s^(-1)`
