Consider the reaction of hydrogen gas (H2) and iodine gas (I2) to form hydrogen iodide (HI) at a certain temperature. If the initial concentrations of hydrogen and iodine are [H2] = 0.5 M and [I2] = 0.3 M, and the equilibrium concentration of hydrogen iodide is [HI] = 0.1 M, what is the value of the reaction quotient (Qc) for this reaction at this temperature?

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
