In the coal-gasification process, carbon monoxide reacts with water to produce carbon dioxide and hydrogen gas. CO (g) + H2O (g) CO2 (g) + H2 (g) In an experiment, 0.35 mol of CO and 0.40 mol of H2O were placed in a 1.00-L reaction vessel. At equilibrium, there were 0.22 mol of CO remaining. Keq at the temperature of the experiment is ________. Group of answer choices 5.5 0.28 0.75 3.5 1.0

Coal gasification produces an easily-transportable, clean-burning combination of carbon monoxide and hydrogen from coal by reacting it with steam, like this: C(s)+H2O(g) → CO(g)+H,(8) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels with 147.0 g of solid carbon and 5.95 g of steam each. The volume and temperature of each vessel is shown in the table below. Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words,...
