For the reaction 4 PH2(g) = 6H2(g) + P (8) the equilibrium concentrations were found to be [PH, 1 = 0.250 M, [H,] = 0.440 M, and [P.) = 0.750 M. What is the equilibrium constant for this reaction? K = The elementary reaction 2H2O(g) =2H,(8) +0,(8) proceeds at a certain temperature until the partial pressures of H,0,H,, and 0, reach 0.059 bar, 0.0014 bar, and 0.0023 bar, respectively, at equilibrium. What is the value of the equilibrium constant at this temperature? K = bar
