Equilibrium: 7. Write the equilibrium expression, K, for the following reactions: 2NH, (g) + CO2 (g) N,CH,0 (s) + H,0 (g) K= N2 (g) + 02 (g) 2 NO (g) K= 8. Consider the following reaction at equilibrium. 2S0, (g) 2S0, (g) + 02 (g) Predict the affect on equilibrium (will it shift left, shift right or no change?): a. Oxygen gas is removed: b. The volume is increased: c. The pressure is increased: d. SO, is added: e. SO, is added:

Consider the following equilibrium: 2NOCI (g) - 2NO (g) + Cl, (g) AG-41. kJ Now suppose a reaction vessel is filed with 4.69 atm of nitrosyl chloride (NOCI) and 4.34 atm of chlorine (CI,) at 641. "C. Answer the following questions about this system: rise Under these conditions, will the pressure of NOCI tend to rise or fall? O fall ? Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fal by adding NO? Similarly, if you said the pressure of NOCI wil tend to fall, can that be changed to a tendency to rise by adding NO? O yes O no Ir you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits.

Consider the equilibrium, 2 NO (g) N2₂ (g) + O₂ (g), 2 for which AH = -180 kJ mol-1. How will adding more N₂ (g) affect an equilibrium mixture of the three gases? Select one: a. Reaction will proceed to the right (in the forward direction) to generate more product. b. Reaction will proceed to the left (in the reverse direction) to generate more product. C. Reaction will proceed to the right (in the forward direction) to generate more reactant. d. Reaction will proceed to the left (in the reverse direction) to generate more reactant. e. There will be no change to equilibrium mixture.
