The reversible elementary liquid reaction 2AC+D is conducted in an isothermal CSTR at a feed rate of 100 dm3/min with an inlet concentration CAo=1.5 mol/dm3. The reaction rate of A in the forward direction is 10 mol/dm3-min and the equilibrium constant is 5. We want to achieve 40% of the equilibrium conversion. Find the size of a CSTR to achieve this conversion. (5 points)
