NEET 2014 · Chemistry · Chemical Equilibrium

For the reversible reaction: N _ 2 (g) + 3 H _ 2 (g) ⇌ 2N H _ 3 (g)...

For the reversible reaction:
N2(g)+3H2(g)⇌2NH3(g)+heat{N}_{2}\left(g\right) + 3{H}_{2}\left(g\right) ⇌ 2N{H}_{3}\left(g\right) + heat
The equilibrium shifts in forward direction:

Options

  1. Aby increasing the concentration of $N{H}_{3}\left(g\right)
  2. Bby decreasing the pressure
  3. Cby decreasing the concentrations of N2(g){N}_{2}\left(g\right) and H2(g){H}_{2}\left(g\right)
  4. Dby increasing pressure and decreasing temperature

Correct answer

D. by increasing pressure and decreasing temperature

Step-by-step solution

It is exothermic reaction due to this for this reaction equilibrium constant is inversely proportional to the temperature.

By increasing the pressure equilibrium will shift towards the lesser number of gaseous moles. Due to this, low temperature and high pressure will be the favourable for the forward direction.

According to Le-Chatalier principle.
