An exothermic reaction is taking place in a constant volume reactor that contains a cooling coil. The reaction A -> B proceeds with a reaction rate constant of k1. The rate of reaction is given as kCA. The feed concentration of A is 4 mol/L, the reaction conversion is 50%, and the reaction rate constant k is 1*10-2 h^-1. The volumetric flow rate remains constant throughout the reaction, at 2 L/hr. The initial temperature in the reactor is 40°C, and the final temperature is 60°C. The heat released at the end of the reaction is 60 j/mol. The amount of heat removed by the coil is 400 j. The density of the mixture is 4 kg/m^3, the Cp value is 20 j/mol.K. If the reactor volume is 4 liters, find the change in temperature over time.
