Question 1: At equilibrium, all reactants are converted to products.

Question 2: At 400 atm pressure, the 350°C curve shows approximately 66% ammonia in the equilibrium mixture.

Question 3: Lower temperatures result in a higher percentage of ammonia at equilibrium.

Question 4: Lower temperatures cause the reaction to be slower.

Question 5: Industrial Haber process plants typically operate at the lowest possible temperature to maximize yield.

Question 6: Higher pressures result in a higher percentage of ammonia at equilibrium.

Question 7: Industrial Haber process plants typically operate at the highest possible pressure to maximize yield.
