Water vapor can react reversibly with solid carbon to yield a mixture of hydrogen gas and carbon monoxide. Suppose you continually add more water vapor to the reaction. In what direction does this shift the equilibrium?
When water vapor reacts reversibly with solid carbon to yield a mixture of hydrogen gas and carbon monoxide and we continually add more water vapor to the reaction the equilibrium of the reaction shifts to the product side.
Because gaseous water is reactant that appears in the reaction quotient expression.
