A+BH2SO4Cr=kCA The reaction (liquid phase) is accomplished in an adiabatic batch reactor where the rate constant is given k=4.71109exp(1.987T32400) The reactor is charged with 1000lbs of a 10wt.%H2SO4 solution in water and 200lbs of propylene oxide at 630R. Assume that the heat capacities for the reactants and products do not vary with temperature. Also assume that the presence of H2SO4 is ignored in the calculation of the heat capacity. Determine the time required to achieve 70% conversion, and the reactor temperature at that point
