The rate constant k, for the reaction N2O5(g) → 2NO2(g) + 
O2(g) is 1.3 × 10-2s-1. Which equation given below describes the change of [N2O5]0 and [N2O5]t correspond to concentration of N2O5 initially and at time t.
O2(g) is 1.3 × 10-2s-1. Which equation given below describes the change of [N2O5]0 and [N2O5]t correspond to concentration of N2O5 initially and at time t.Options
A.[N2O5]t = [N2O5]0 + kt
B.[N2O5]0 = [N2O5]t ekt
C.log[N2O5]0 = log [N2O5]t + kt
D.In 
= kt 1
= kt 1Solution
As the unit of rate constant is sec-1, so the reaction is first roder reaction. Hence k = 
= log 
or kt = log 
= log or kt = log Create a free account to view solution
