Consider the following reaction: 2 P(e) + 3 H2) 2 PH3(2) (assume P) is white P) a) Use tabulated data in the text to calculate K, for this reaction at 298 K. b) Use tabulated data in the text to determine K, at 550 K assuming AH°R is independent of temperature. c) Assuming the reaction is begun with n, moles of H2, excess Pe), and no PH3, derive a relationship between K, and eq. d) Solve for čeq at 298 K (assume a total pressure of 50 bar) and then use this to determine the equilibrium partial pressures of the two gases. Note: AHO of Po white = 0 kJ mol-1; AG© of Pe) white = 0 kJ mol-1 AHe of H22) = 0 kJ mol-1 ; AGe of H22) = 0 kJ mol-1 AHE of PH3(2) = 5.4 kJ mol-1; AGE of PH3(e) = 13.5 kJ mol-1 Consider the following reaction: 2 P(e) + 3 H2) 2 PH3(2) (assume P) is white P) a) Use tabulated data in the text to calculate K, for this reaction at 298 K. b) Use tabulated data in the text to determine K, at 550 K assuming AH°R is independent of temperature. c) Assuming the reaction is begun with n, moles of H2, excess Pe), and no PH3, derive a relationship between K, and eq. d) Solve for čeq at 298 K (assume a total pressure of 50 bar) and then use this to determine the equilibrium partial pressures of the two gases.
