Equilibrium - Result Question 25

####26. For the reversible reaction,

N2(g)+3H2(g)2NH3(g)+ heat

[2014]

The equilibrium shifts in forward direction

(a) By increasing the concentration of NH3(g)

(b) By decreasing the pressure

(c) By decreasing concentration of N2(g) and H2(g)

(d) By increasing pressure and decreasing temperature.

Show Answer

Solution:

  1. (d) 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.
