Consider the equation O 2 (g)+ 2H 2 (g)⇔ 2H 2 O (g). Increasing the concentration of hydrogen gas will ________.

Increasing the concentration of a reactant (in this case, hydrogen gas) will shift the equilibrium of the reaction to the right, favoring the formation of more product (in this case, H2 2 O).
