The equilibrium of 2H 2 O (g) 2H 2 (g) + O 2 (g) at 2,000 K has a Keq value of 5.31 x 10-10. What is the Keq expression for this system? (Enter subscripts after the letters: for example, H2O = Hs2O. Also, dont forget to use proper chemical shorthand for chemical symbols. For instance, chlorine = Cl but not cl or cL.)

The KEQ expression is always the concentration of the products over the concentration of the reactants, with each substance raised to a power equal to its stoichiometric coefficient.

In general, if aA + bB ⇆ cC + dD

then K (EQ) = [C]^c*[D]^d / [A]^a*[B]^b
