Design a continuous stirred tank reactor (CSTR) for the exothermic reaction A + 2B -> C with the following conditions: - The reactor should produce a minimum of 5 moles of product C per hour- The feed ratio of A to B should be 1:2- The temperature of the reactor should not exceed 50°C- The volumetric flow rate of reactant feed is 10 L/hour- The reactor should have a residence time of at least 4 hours. Assuming all reactants are available in excess, determine:- The required volume of the CSTR- The heat generated by the reaction- The cooling rate required to maintain the reactor temperature below 50°C

Calculate the entropy change (ΔS) for the combustion of methane gas (CH4) at constant pressure and standard conditions, given the following data: C(s) + O2(g) → CO2(g) ΔS° = -394 J/K·mol 2H2(g) + O2(g) → 2H2O(l) ΔS° = -237 J/K·mol CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔH° = -802 kJ/mol
