NEET · Chemistry · STD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)
For the reversible reaction, \(N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)} + \) heat The equilibrium shifts in forward direction
- A by increasing the concentration of \(NH_{3(g)}\)
- B by decreasing the pressure
- C by decreasing the concentrations of \(N_{2(g)}\) and \(H_{2(g)}\)
- D by increasing pressure and decreasing temperature.
Answer & Solution
Correct Answer
(D) by increasing pressure and decreasing temperature.
Step-by-step Solution
Detailed explanation
Any change in the concentration, pressure and temperature of the reaction results in change in the direction of equilibrium. This change in the direction of equilibrium is governed by Le-Chatelier's principle. According to Le-Chatellier's principle, equilibrium shifts in die opposite direction to undo the change. \(\mathrm{N}_{2}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{g}) \rightleftharpoons 2 \mathrm{NH}_{3}(\mathrm{g})+\mathrm{Heat}\)
