NEET2014ChemistryChemical EquilibriumActual
For the reversible reaction: N 2 g + 3 H 2 g ⇌ 2 N H 3 g + h e a t The equilibrium shifts in forward direction:
Options
- Aby increasing the concentration of N H 3 g
- Bby decreasing the pressure
- Cby decreasing the concentrations of N 2 g and H 2 g
- 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.
