Yes it is possible to study the kinetics of this reactionina a constant volume batch reactor, by following the change in total pressure with repect to time. The reaction is endothermic and hence temperature to be maitained higher levels by varying the pressures. Concentration dependence term can be obtained from batch reactor at particular temperature and then temperature dependence of rate constants can be obtained by varying temperatures by change in total pressure.

In a study of the gas phase decomposition of sulfuryl chloride at 600 K SO2Cl2(g)SO2(g) + Cl2(g) the concentration of SO2Cl2 was followed as a function of time. It was found that a graph of ln[SO2Cl2] versus time in minutes gave a straight line with a slope of -4.12×10-3 min-1 and a y-intercept of -7.31 . Based on this plot, the reaction is order in SO2Cl2 and the rate constant for the reaction is min-1.
