Design a chemical reactor with a capacity of 100 liters and determine the operating conditions (temperature, pressure, and flow rate) required to achieve a 95% yield of product X in a specific reaction. The reaction rate constant is known to be 0.1/min and the initial concentration of reactant A is 2 mol/L. Use the design equation for a first-order irreversible reaction and assume a constant density of the reaction mixture.
