Time required to decompose SO2Cl2to half of its initial amount is 60 minutes. If the decomposition is a first order reaction, calculate the rate constant of the reaction.
We know that for a 1st order reaction,
t½ = 0.693 / k
It is given that t1/2= 60 min
k = 0.693 / t½
= 0.693 / 60
= 0.01155 min-1
= 1.155 min-1
Or
k = 1.925 x 10-2 s-1
