a) Calculate the entropy of mixing 3 mol of hydrogen with 1 mol of nitrogen. b) Calculate the Gibbs energy of mixing at 25 °C. c) At 25 °C, calculate the Gibbs energy of mixing 1 – 3 mol of nitrogen, 3(1 – 3) mol of hydrogen, and 25 mol of ammonia as a function of 5. Plot the values from = 0 to = 1 at intervals of 0.2. d) If AG;(NH3) = − 16.5 kJ/mol at 25 °C, calculate the Gibbs energy of the mixture for values of = 0 to 3 = 1 at intervals of 0.2. Plot G versus & if the initial state is the mixture of 1 mol N₂ and 3 mol H₂. Compare the result with Figure 11.5. e) Calculate G for at p = 1 atm.
