The chemical reaction given below :
`Cl_(2)(g)+SO_(2)(g) +2H_(2)O(l) rarr 2Cl^(-) (aq.) +3H^(+) (aq.)+ HSO_(4)^(-) (aq.)`
proceeds readily in aqueous acid solution.
(i) Give the half-cell reactions.
(ii) If a fully charged cell initially held 1 mole of `Cl_(2)` for how many days could it sustain a current of 0.05 ampere, assuming the cell becomes non0operative when 90% of initial `Cl_(2)` has been used up ?

Answer

40.2 days
