For a I order reaction A toBthe reaction rate at reactant concentration 0.01 M is found to be 2.5 xx 10^(-5) Ms^(-1). The half life period of the reaction is

Answer»

30s
300 s
220 s
347 s

Solution :rate `=k[A]^1`
`k = (2.0xx 10^(-5))/0.01 = 2.0 XX 10^(-3)s^(-1)`
`:.t_(1//2)= 0.693/k = 0.693/(2XX 10^(-3))= 347s`
