The following reaction between hydrogen and oxygen takes place in a closed container and at a temperature that maintains the water vapor in the gas phase: 2 H₂O(g) ⇌ 2 H₂(g) + O₂(g). In one experiment, the equilibrium concentrations of the gases are as follows: [H₂] = 2.0M, [O₂] = 3.0M and [H₂O] = 4.0M. Calculate the value of Keq for this reaction.
