We’re given the following first order reaction:

SO2Cl2  SO2 + Cl2

The integrated rate law for a first order reaction is as follows: where:

[A]t = concentration at time t

k = rate constant

t = time, [A]0 = initial concentration

We’re being asked to determine the time it would take for the reaction to be 95% completeSince no concentration is given, we can use the given percentages in place of concentration.
