Question
IN QUES OF RXn Fe 2+ + 2e- ---> Fe THE E* GIVEN IS -VE 0.405 &I WANT TO KNOW IN THE LAST STEP WHY3/2F(0.4) IS USED
IN RXn CO2 +C---> 2CO IN INITIAL WE TAKE XFOR CO2 BUT FOR FINAL Y 2X +1 -X=1.2 IS USED.
Joshi sir comment
for any reaction obtained by other two reactions formula used will be nE = n'E' + n''E''
in second question 2x is used because x litre CO2 will give 2x litre CO
