Question:

Steam enters a heat exchanger operating at steady state. An equilibrium mixture of H2O, H2, O2, H, and OH exits at 2500 K and 100 kPa. Determine the
(a) Equilibrium composition of H2O (in kmols) and
(b) Heat transfer (q) to the surroundings per unit mass of steam. Assume the surroundings to be 300 K and 100 kPa.
