Ammonia synthesis is performed in a multibed catalytic reactor; see Fig. P5.19.

Each bed operates adiabatically and the reactor employs indirect cooling. Compute the conversion reached after two catalytic

beds if only 50% of the equilibrium conversion is reached. The feed to the first bed is 400C, and after each bed the feed is cooled to 400C.
Total pressure is 300 atm. Data for the equilibrium and the energy balance:
