sir in this question we have used equation G=nFE to get the E of resultant reaction but, sir in 2014 jee main (offline) their was same question and we have just added or subtracted the two reactions to get the E of the resultant. Sir please clear my doubt i have attached the image of question which came in AIEEE 2009 in which G=nFE is used ?
