Figure, shows an electrolyte of `AgCI` through which a current is passed. It is observed that `2.68g` of silver is deposited in 10 minutes on the cathode. Find the heat developed in the `20 Omega` resistor during this period. Atomic weight of silver is `107.9 g mol^(-1)`. (Figure)

Explanation

`m = (Eit)/(F) ` ltbr. `i=(mF)/(Et) = (2.68xx96500)/(107.9xx10xx60)=4A`
`H = i^2RT = (4)^2 xx 20 xx 10 xx 60`
`=192xx10^3 J`
`=192kJ`.
