Time ; [PAN]
0 min 5.0 x 1014  molecules L-1
30 min 2.5 x 1014 molecules L-1
60 min 1.25  x 1014 molecules L-1
At 30 min, 50% reaction takes place.
At 60 min, 75% reaction takes place.
Thus,   T75 = 2 x T50
it is valid for first order reaction. Thus, order = 1
For first order reactions, T50 = 0.693/k
