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.

we have for the first order reaction
k=2.303/tlog[A0]/[A]
k=rate sonstant
A0=initial concentration
A=final concentration ,hereA=A0/2
t=time taken for the decomposition
=2.303/(60)log[A0]/[A0/2]
=.011 min^-1
Therefore the value of the rate constant is .011 min^-1.
