The decomposition of dinitrogen pontoxide(N_2O_5) follows the first order rate law . Calculare the rate constant from the given data :

Answer»

Solution :APPLYING the formula,
`K=(2.303)/((t_2-t_1))LOG10([A_1])/([A_2])`
`=(2.303)/((1600-800))log 10 (1.45)/(0.88)=(2.303)/(800)xx0.2169`
`=6.24xx1^(-4)"sec"^(-1)`
