In which of the following cases equilubrium constants are affected

Question

Volume of the flask in which the following equilibria are separately established are transferred to a flask

Answer 1

The correct options are a and c

• The volume is doubled. hence, the pressure is reduced to half. 
• Those reactions which have non zero value of Δn will be affected by the pressure change. 
• The value of Δn for reactions of options A, B, C, and D are -2,0 and 1 respectively. Thus the equilibrium of the reactions A and C will be affected.
