Design a chemical reactor for the exothermic reaction A + B -> C, given the following parameters: - The reaction takes place at a temperature of 500°C- The reaction rate constant is 0.05 L/mol/min- The feed stream contains both A and B in equal molar amounts, with a total flow rate of 100 L/min- The desired product, C, should have a concentration of at least 90% in the reactor effluent stream- The reactor should have a residence time of at least 5 minutes. Determine the type of reactor (batch, plug flow, or continuously-stirred tank) and the dimensions (volume, length, diameter) required to achieve the desired product concentration and residence time, assuming an isothermal and well-mixed reactor.
