ChemistryEquilibriumJEE Main

A mixture of N₂ and H₂ in the mole ratio 1:3 is allowed to attain equilibrium when 50% of mixture has reacted. If P is the equilibrium pressure, then partial pressure of NH₃ formed is:

Answer: (C)

Solution

Initial total=4; 50% N₂ reacted: ΔN₂=0.5,ΔH₂=1.5,NH₃=1.0. Total eq.=4−0.5−1.5+1=3. Mole fraction NH₃=1/3, P(NH₃)=P/3.
