	How many kilo joules of energy is expended during the passage of a current of 0.1 A for 100 sec under a potential of 150 V
	Calculate the useful work done during the reaction $Ag\,(s)+\frac{1}{2}C{{l}_{2}}(g)\to AgCl\,(s)$ Given that $E_{C{{l}_{2}}/C{{l}^{-}}}^{0}=+1.36V$ and $E_{AgCl,\,Ag,\,C{{l}^{-}}}^{0}=+0.220V$ if ${{P}_{C{{l}_{2}}}}=1$ and T = 298K
	A solution containing ${{H}^{+}}$ and ${{D}^{+}}$ ions is in equilibrium with a mixture of ${{H}_{2}}$ and ${{D}_{2}}$ gases at ${{25}^{o}}C$. If the partial pressures of both the gases are 1.0 atm, calculate the ratio $[{{D}^{+}}]/[{{H}^{+}}]$ $(E_{{{D}^{+}}/D}^{0}=-0.003V)$
	Benzoic acid solution is titrated with NaOH conductometrically, graphical representation of the titration is
	If NaOH is titrated with HCl, variation of conductance y-axis with addition of HCl (x-axis) will be
