Question:

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.

Answer:

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
