Chemical Equilibrium question

2014 · Q112

NEETChemistryChemical EquilibriumMCQ+4 / −1
For the reversible reaction,
N2(g) + 3H2(g) ⇌\rightleftharpoons⇌ 2NH3(g) + heat

The equilibrium shifts in forward direction
  1. A
    by increasing the concentration of NH3(g)
  2. B
    by decreasing the pressure
  3. C
    by decreasing the concentrations of N2(g) and H2(g)
  4. D
    by increasing pressure and decreasiing temperature.

Correct answer: D

According to Le-Chatelier’s principle, the equilibrium shifts in that direction so as to oppose the applied change.

Given reaction is exothermic reaction. Hence according to Le-Chatelier's principle low temperature favours the forward reaction and on increasing pressure equilibrium will shift, towards lesser number of moles i.e. forward direction.
