`"Anode: "2Cl^(-)(aq)rarr Cl_(2)(g)+2e , E_("Red")^(@)=+1.36V`
`"Cathode : "2H_(2)O(l)+2e rarr H_(2)(g)+2OH^(-)(aq)' E_("Red")^(@)=-0.83V.` Cell reaction : `2Cl^(-)(aq)+2H_(2)O(l)rarr H_(2)+Cl_(2)+2OH^(-)(aq)`. Which of the following statement is correct -

A

under standard conditions, the overall reaction is spontaneous
