Design a continuous stirred-tank reactor (CSTR) for the exothermic reaction of A + B → C with a rate constant of 0.05 L/mol/min. The reactor should produce a minimum of 500 g of C per minute, while maintaining a conversion of at least 90%. The feedstream of A and B is available with a flow rate of 2 L/min and an initial concentration of 1 M for both reactants. The reactor should be operated at a temperature of 50°C and a pressure of 1 atm. What should be the volume of the CSTR and the flow rate of the cooling medium used to maintain the desired temperature?

An industrial process involves the reaction of nitrogen gas and hydrogen gas to produce ammonia gas, in the presence of a catalyst. If the equilibrium constant for this reaction at a certain temperature is 6.2 × 10^-2 and the initial concentrations of nitrogen and hydrogen gases are 1.2 M and 0.8 M respectively, what would be the equilibrium concentrations of the reactants and products if the catalyst increases the rate of the forward reaction by a factor of 4?

A student needs to find out how much heat is released or absorbed when 100 mL of 0.1 mol/L solution of barium chloride (BaCl2) is mixed with 150 mL of 0.1 mol/L solution of sodium sulfate (Na2SO4) at 25°C. Given the enthalpy of precipitation of BaSO4 as -256 kJ/mol, calculate the enthalpy change (in kJ) for the reaction that occurs and determine whether the reaction is exothermic or endothermic.

A chemistry student needs to determine the effect of increasing the pressure on the equilibrium position of a reaction. Consider the following reaction at equilibrium: N2(g) + 3H2(g) ⇌ 2NH3(g) If the pressure is increased, will the reaction shift to the left or right, and in what direction will the reaction quotient, Q, shift as a result? Justify your answer using Le Chatelier's principle.
