Time required to decompose SO_(2)Cl_(2) to half of its initial amount is 60 minutes. If the decomposition is a first order reaction, calculate the rate constant of the reaction.

Answer»

Solution :For a first order reaction,
`K=(0.693)/(t_(1//2))=(0.693)/("60 minutes")=1.155xx10^(-2)"minutes"^(-1)`
or `k=(0.693)/(60xx60s)=1.925xx10^(-4)s^(-1).`
