Calculate the standard Gibbs free energy of formation for NH3 (g) at 350 K.
a) The synthesis of ammonia at room temperature is slow. Would raising the temperature help produce more ammonia? Explain your reasoning.
b) What direction will the reaction proceed if, at 350 K, you have a mixture that contains N2 gas at a partial pressure of 1.5 atm, H2 gas at a partial pressure of 0.75 atm, and NH3 gas at a partial pressure of 0.5 atm?
