One mole of PCl5(g) dissociates and attains equilibrium after t seconds at 27∘C: PCl5(g)⇋PCl3(g)+Cl2(g) At equillibrium, the vapour density is found to be 100 and the volume of the system is 10.425 L at 27∘C. The total pressure of the system at equilibrium will be atm. R=0.082 Latmmol−1K−1

Answer» One mole of PCl5(g) dissociates and attains equilibrium after t seconds at 27C:
PCl5(g)PCl3(g)+Cl2(g)
At equillibrium, the vapour density is found to be 100 and the volume of the system is 10.425 L at 27C.
The total pressure of the system at equilibrium will be atm.
R=0.082 Latmmol1K1
