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_6("sol" ..) overset(C Cl_4)(rarr) 2NO_("sol" ..) + 1/2 O_2 (g)`
(a) Rate = `k [N_2O_5]`
`= 6.2 xx 10^(-4) xx 2.5`
` = 1.55 xx 10^(-3)" mollit"^(-1)`
Rate = `4.2 xx 10^(-3) "mol lit"^(-1) "sec"^(-1)`
`k = 6.2 xx 10^(-4) sec^(-1)`
`(N_2O_2) = ?`
` 4.2 xx 10^(-3) = 6.2 xx 10^(-4) xx [N_2O_2]`
`[N_2O_2] = 6.67 "mol lit"^(-1)`
