Q.

Which one of the following conditions will favour maximum formation of the product in the reaction A2(g)+B2(g)X2(g),  ΔrH=-X kJ     [2018]

1 Low temperature and high pressure  
2 Low temperature and low pressure  
3 High temperature and high pressure  
4 High temperature and low pressure  

Ans.

(1)

On increasing the pressure and decreasing the temperature, equilibrium will shift in forward direction.
