Question 78

Multiple Choice

Consider the following reaction at equilibrium: 2NH3 (g) Consider the following reaction at equilibrium: 2NH<sub>3</sub> (g)    N<sub>2</sub> (g) + 3H<sub>2</sub> (g) ΔH° = +92.4 kJ Le Châtelier's principle predicts that adding N<sub>2</sub> (g) to the system at equilibrium will result in __________. A) a decrease in the concentration of NH<sub>3</sub> (g)  B) a decrease in the concentration of H<sub>2</sub> (g)  C) an increase in the value of the equilibrium constant D) a lower partial pressure of N<sub>2</sub> E) removal of all of the H<sub>2 </sub>(g) N2 (g) + 3H2 (g) ΔH° = +92.4 kJ
