During electrolysis of sulphuric acid, which of the following processes is possible at anode? A. \( 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \longrightarrow \mathrm{O}_{2}(\mathrm{~g})+4 \mathrm{H}^{+}(\mathrm{aq})+4 \mathrm{e}^{-} \underset{\mathrm{E}_{\text {cell }}}{\ominus}+1.23 \mathrm{~V} \) B. \( 2 \mathrm{SO}_{4}^{2-}(\mathrm{a} \mathrm{q}) \longrightarrow \mathrm{S}_{2} \mathrm{O}_{8}^{2-}(\mathrm{aq})+2 \mathrm{e}^{-} \quad \mathrm{E}_{\text {cell }}^{\ominus} 1.96 \mathrm{~V} \) Choose the correct option based on following statements. (i) Process \( \mathrm{A} \) is preferred at higher concentration of sulphuric acid. (ii) Process \( \mathrm{B} \) is preferred at higher concentration of sulphuric acid. (iii) Process A is preferred for dilute sulphuric acid. (iv) Process \( B \) is preferred for dilute sulphuric acid. (v) Both \( \mathrm{A} \) and \( \mathrm{B} \) are equally possible at higher concentration. (a) (v) and (iii) (b) (iii) and (ii) (c) (i) and (iv) (d) (v) and (iv) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
