The decomposition of `N_2 O_5` in carbon tetrachloride solution has been found to be first order with respect to `N_2 O_5` with rate constant, `k-6.2xx10^-4s6-1`
`N_2 O_5(G)rarr2NO_2(g)+1/2O_2(g)`
Calculate the rate of reaction when
`[N_2 O_5]=2.50mol L^-1`

Explanation

`N_2O_5 overset(C Cl_4)(rarr) 2NO_2 + 1/2 O_2`
(i) Rate of `ra^(..) = k [N_2O_5]`
`= 6.2 xx 10^(-4) xx 2.50 `
`= 1.55 xx 10^(-3) mol l^(-1) sec^(-1)`
(ii) Rate of `ra^(..) = k [N_2O_5]`
`= 6.2 xx 10^(-4) xx 0.5`
` = 3.1 xx 10^(-4) mol l^(-1) sec^(-1)`
