An equilibrium constant
#overbrace(color(red)(2)"H"_2"O"(g))^"reactant" rightleftharpoons overbrace(color(red)(2)"H"_2(g) + color(red)(1)"O"_2(g))^"products"#
The mass action expression is written with products on top and reactants on the bottom.
#color(blue)(K_(eq) = overbrace((["H"_2]^color(red)(2)["O"_2])/(["H"_2"O"]^color(red)(2)))^"mass action expression")#
Remember to exclude the pure liquids and solids. Only include aqueous and gaseous substances.
Well for
Explanation:
For the given, gas-phase equation, each reagent and product is raised to the power of its stoichiometric coefficient......i.e.
....which looks like
