Question
Time required to decompose SO2Cl2 to half of its initial amount is 60 minutes. If the decomposition is a first order reaction, calculate the rate constant of the reaction.

Solution
Given: Time (t) = 60 minutes
We know that for a first-order reaction,
k = `0.693/(t_(1//2))`
= `0.693/(60 min)`
= 1.155 × 10−2 min−1
or,
k = `0.693/(60 xx 60 s)`
= 1.925 × 10−4 s−1
