NEET Chemistry Le Chatelier's Principle MCQ Question
For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g), how will the equilibrium position shift if the pressure is increased by decreasing the volume of the reaction vessel?
Shift to the right, favoring NH3 formation.
Shift to the left, favoring N2 and H2 formation.
No shift, equilibrium is unaffected by pressure.
Shift depends on initial concentrations.
Correct Answer
Detailed Explanation
Increasing pressure by decreasing volume favors the side with fewer gas moles. Here, 4 moles of reactants form 2 moles of NH3, so the equilibrium shifts right.
