question 34

Multiple Choice

The formation of ammonia from elemental nitrogen and hydrogen is an exothermic process. $\mathrm{N}_{2}(g) +3 \mathrm{H}_{2}(g) \rightleftharpoons 2 \mathrm{NH}_{3}(g) \quad\quad\quad\quad\quad\quad \Delta H^{\circ}=-92.2 \mathrm{~kJ} / \mathrm{mol}$
Assuming the reaction is at equilibrium,which one of the following changes will drive the reaction to the right?

• A) adding ammonia
• B) increasing the temperature
• C) increasing the pressure
• D) removing hydrogen
• E) adding a catalyst
