In the coalgasification process, carbon monoxide is converted to carbon dioxide via the following reaction: CO (g) + H2O (g) ? CO2 (g) + H2 (g) In an experiment, mol of CO and mol of H2O were placed in a reaction vessel. At equilibrium, there were mol of CO remaining. Keq at the temperature of the experiment is _____.

Gasification is a mature process for converting hydrocarbons into electric power, clean synthesis gas, fertilizers, fuels and chemicals with minimum environmental impact. Powerful antifoulants can improve runtime and profitability when fouled syngas coolers or soot scrubbers are causing bottlenecks.

Gasification may occur in a separate processing facility or a coal mine. The gases can be stored or burned for the production of electricity, fuel or chemicals. Gasification usually involves the use of oxygen and steam. This process offers several advantages and disadvantages with regard to efficiency, cost, the environment and other factors.
