Calcaulte the standard free energy change taking place in H_(2)//O_(2) fuel in which the following reactions occurs: (i) O_(2)+4H^(+) to 4e^(-)to2H_(2)O,E^(@)=1.229V (ii) 2H_(2)to4H^(+)+4e^(-),E^(@)=0.000V |

Answer» SOLUTION :`E_(CELL)^(@)=E_(O_(2)//H_(2)O)^(@)(RED)+E_(H_(2)//H^(+))^(@)(Ox)=1.229+0=1.229V` `DeltaG=-nFE_(cell)^(@)=-4xx96500xx1.229J=-474.4kJ`. |
