A reactor is fed initially with 100 moles of reactant B (V=10 L). A at a concentration of 1 M is slowly added to the reactor over a course of 12 hr at T= 250C. The following exothermic reaction (Standard heat of reaction is -80 kJ/mol) takes isothermally at T= 70°C. k A+B C (rck CA) Where, k=0.15 hr. Determine the following: = 1.1. The concentration of A and product C in the reactor as a function of time if A is added at a constant flow rate of 2 L/hr. 1.2. The concentration of A and product C in the reactor as a function of time if A is added exponentially at a rate of (0.5 0.2t). 1.3. The heat released from the reactor at the end of the run for both operational modes If Cp is 50 J/mol/K.

A reactor is fed initially with 100 moles of reactant B (V=10 L). A at a concentration of 1 M is slowly added to the reactor over a course of 12 hr at T= 250C. The following exothermic reaction (Standard heat of reaction is -80 kJ/mol) takes isothermally at T= 70°C. k A + B →C Where, k= 0.15 hr'. Determine the following: = k CA) 1.1. The concentration of A and product C in the reactor as a function of time if A is added at a constant flow rate of 2 L/hr. 1.2. The concentration of A and product C in the reactor as a function of time if A is added exponentially at a rate of (0.5 e0.2t). 1.3. The heat released from the reactor at the end of the run for both operational modes If Cp is 50 J/mol/K.
