Which of the following cell can produce maximum electrical work? `["Given" : P_(H_(2))=1 atm, K_(a)(CH_(3)COOH)=K_(b)(NH_(4)OH)=10^(-5)]`A. `Pt|H_(2)(g)|0.1MNH_(4)Cl(aq.)||0.1MCH_(3)COOH(aq.)|H_(2)(g)|Pt`B. `Pt|H_(2)(g)|0.1MHNO_(3)(aq.)||0.1MKOH(aq)|H_(2)(g)|Pt`C. `Pt|H_(2)(g)|0.1MHCl(aq.)||0.1MCH_(3)COOK(aq.)|H_(2)(g)|Pt`D. `Pt|H_(2)(g)|0.1MCH_(3)COONa(aq.)||0.1MHCl(aq.)|H_(2)(g)|Pt` |

Answer» Correct Answer - D For maximum electrical work `E_("cell")` = Maximum `E_("cell") = 0.0591"log" ([H^(+)]_(c))/([H^(+)]_(a))" "[H^(+)]_(c)gt[H^(+)]_(a)` `therefore` Anodic compartment should be more basic and cathodic compartment should be more acidic. |
