Calculations for Isothermal Reaction

In a chemical plant one of the products produced is carbon monoxide, CO. It is proposed to utilize this CO by reacting it with water to form hydrogen gas. The "unbalanced" chemical equation is

CO + H2O ---> CO2 + H2

If the CO and H2O come into the reaction chamber at 0.1 MPa and 400 K, what is the required heating for an isothermal reaction?

...O2 ------ > CO2 Hf3 = -94.052 Kcal/mole

The total Heat of Reaction is equal to :

Hreact = Hf3 - ( Hf1 + Hf2) = -94.052 - ( -24.416 - 57.8 ) = - 11.836 Kcal/mole

The reaction is endothermic, such a way you should supply this amount of energy if you want to keep ...
