a. Calculate the equilibrium constant for this reaction at 25°C.
b. Is a mixture of the three gases where
P_N2 = 3.5 bar,
P_H2 = 1.2 bar, and
P_NH3 = 0.22 bar at equilibrium? Justify your answer.
c. What is the value of DG under the conditions of Part b?
d. Compare the answer from Part c with DG°. Explain the difference observed.
