Chapter 15.6, Problem 9P

You have 1.5 moles of pure water and 1 mole of CO, both at 258C and 1 bar. You want to mix them together to make carbon dioxide by the following gas phase reaction at 500 K:

CO + H₂O → CO₂ + H₂

Once the reaction is at equilibrium, you want to heat up the resulting mixture to 750 K. This heating is done quickly enough that it can be assumed no reaction occurs; the equilibrium composition at 500 K is still the composition at 750 K. The entire process is to be carried out at 1 bar.

What is the TOTAL heat load required for this process (from 258C to 750 K)? Will you be adding heat overall or removing heat?
