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.


Answer
Given that half life, t1/2 = 60 min = 60 x 60 = 3600 sec (1 min = 60 sec)
The formula of half life for the a 1st order reaction,

Plug the value we get

Solve for the value of k we get

After calculation we get

= 1.925 x 10-4 s-1
Do you know any other method of solving this problem ?
