A reaction used in the production of gaseous fuels from coal, which is mainly carbon, is C(s) 1 H2O(g) Δ CO(g) 1 H2(g).
(a) Evaluate K At 900 K, given that the standard Gibbs free energies of formation of CO(g) and H2O(g) at 900 K are 2191.28 kJ/mol and 2198.08 kJmol, respectively. (b) A sample of graphite of mass 5.20 kg and 125 g of water were placed into a 10.0-L container and heated to 900 K. What are the equilibrium concentrations?

Are we supposed to use an ICE table in part b of this problem?

Yes an ICE table is needed in part b. Once you find the moles of each substance using the given moles, use an ice table to find equilibrium concentrations.

You would need to use an ICE table for part b, to find the eventual equilibrium concentrations of the substances involved.

Yes you would in order to find the equilibrium concentrations
