Question

A crucial reaction for the production of synthetic fuels is the conversion of coal to H2 with steam.

C(s) H2O(g) CO(g) H2(g)

(a) Calculate ∆Go for this reaction at 25 degrees Celsius, assuming C(s) is graphite.

(b) Calculate Kp for the reaction at 25 degrees Celsius.

(c) Is the reaction predicted to be spontaneous under standard conditions? If not, at what temperature will it become so?

(d) Calculate the temperature at which the equilibrium constant for the reaction is 1.0 x 10-4.

Answer 1

C(s) H2O(g) ---> CO(g) H2(g)

∆G° = -R*T*LnKp

Kp = P(H2)*P(CO) / P(H2O)
