Following is first order reaction:
`N_(2)O_(5)` ("solution") `to2NO_(2) ("solution")+(1)/(2)_(O_(2)(g)) ` In which `CCl_(4)` is a solute .It is k=`5.0xx10^(-4)S^(-1)`
The concentration of `N_(2)O_(5)` in initial is 0.25 mol `L^(-1)`
(i)What will be the rate of reaction initially?
(ii)Calculate half life `(t_(1)/(2))`
(iii)How much time require to compute 75 % reaction ?
(iv)Calculate the concentration of `N_(2)O_(5)` and NO after 30 min .

Explanation

(i)`1.25xx10^(-4)` mol `L^(-1) s^(-1)` (ii) `t_((t)/(2))=1386s`
(iii) 2773 s (iv) `[N_(2)O_(5)]=0.1 mol L^(-1)` and `[]NO_(2)=0.30 mol L^(-1)`
