→$4.0\,moles$ of argon and $5.0\, moles$ of $PCI _{5}$ are introduced into an evacuated flask of $100\, litre$ capacity at $610\, K$. The system is allowed to equilibrate. At equilibrium, the total pressure of mixture was found to be $6.0 \,atm$. The $K _{ p }$ for the reaction is ...... [Given : $R=0.082 \,L \,atm\, K ^{-1}\, mol ^{-1}$ ]
→The resistance of conductivity cell containing $0.01\, M\, KCl$ solution at $298\, K$ is $1750 \,\Omega$. If the conductively of $0.01\, M \,KCl$ solution at $298\, K$ is $0.152 \times 10^{-3} \,S \,cm ^{-1}$, then the cell constant of the conductivity cell is $..........\,\times 10^{-3} \,cm ^{-1}$.
