The irreversible reaction, A + B → C, in liquid phase is carried out in a non-isothermal 200 L batch reactor. The reaction is first order with respect to both reactants. The reactor is loaded with A and B, whose concentrations are CAo=0.5 mol/L and CBo=0.6 mol/L. The heat of reaction is -15 kJ/mol and is independent of temperature. The initial temperature of the reactor of 27 ºC is obtained by passing a fluid through the reactor jacket. The average heat capacities are: CpA=CpB=65J/(mol K) and CpC=150 J/(mol K). The global heat exchange coefficient and the heat exchange area are related by UxA= 50 J/(sK). The speed constant is given by: a) Determine the reaction time required to obtain a conversion of 80%;
