In the study of the reaction – Cl₂ + PCl₃ ⇌ PCl₅ partial pressures of Cl₂, PCl₃ and PCl₅ at equilibrium are 0.1, 0.1 and 0.2 atm respectively at 250° C. At the same temperature, in another experiment on the same reaction, at equilibrium the partial pressures of PCl₃ and Cl₂ are half those in the first experiment. The partial pressure of the PCl₅ at equilibrium in the second experiment is –
A
One-fourth of the first
B
Half of the first
C
One-eighth of the first
D
One-third of the first
