1. The rate of the homogeneous gas-phase reaction: A + 3 B 2X + Y has been studied. Some of the data are: Run Initial pressure A Initial pressure B Initial total pressure change rate p/torr p/torr (-dP/dt)/(torr/s) 1 352 153 3.44 3 289 6.55 247 617 8.14 (a) What are the orders of the reaction with respect to A and with respect to B? (b) Assume that the gas mixture is ideal and find the relation between the usual rate of reaction, v, and d/dt, where is the total pressure. The volume is constant. 392
