Answer»

On heating, arsine (AsH3) decomposes according to first order kinetics as follows:

2AsH3(g)2As(s)+3H2(g)

The total pressure measured at constant temperature and constant volume varies with time as given:


















t (min)057.510
Pt (mm Hg)760836866897



Calculate the rate constant from above data

Take:

log(1.25)=0.096log(1.38=0.142log(1.56)=0.194
