4. At 25.0°C, the equilibrium constant for the reaction 3 H₂(g) + N₂(g) → 2 NH3(g) is 5.9 x 106. The enthalpy of formation for NH3(g) at this temperature is -46.1 kJ/mol. Assuming that AHⓇ and AS° does not vary with the temperature, calculate the values of AHO, ASO, AGO, and K for this reaction at 50.0°C. (Answer: -92.2 kJ, -180 J/K, -34 kJ, 3.2 x 105)
