Consider a gas phase reaction A>2B, conducted isothermally and at constant pressure in a batch reactor. Initially, the reactor contains 1 moles A,0.5 moles of B and 1 moles of inert materials. The reaction is second order with a rate constant of 0.5Lmol1s1. Initial reactor volume is 20L. Determine the time(s) required for 70% conversion 225 557 864 374 111
