In a study of the reaction 3 Fe ( s ) + 4 H 2 O ( g ) ⇌ Fe 3 O 4 ( s ) + 4 H 2 ( g ) at 1200 K it was observed that when the equilibrium partial pressure of water vapor is 15.0 torr, the total pressure at equilibrium is 36.3 torr. Calculate the value of K p for this reaction at 1200 K. ( Hint: Apply Dalton's law of partial pressures.)
