The decomposition of N₂O_5(g) at 320K according to the following equation follows first order reaction:

`N_2O_(5(g))->2NO_(2(g))+1/2O_(2(g))`

The initial concentration of N₂O_5(g) is 1.24 x 10^-2 mol. L-1 and after 60 minutes 0.20x10^-2 molL^-1. Calculate the rate constant of the reaction at 320K.
