In an electrochemical cell, the electromotive force, EMF is the potential difference across the electrodes The standard state of EMF of a cell E not is equal to emf of a cell when all the participating species are at unit active masses Some important characteristics of E not are 1. E is not an intensive property that is E does not depend upon the amount For example in the below reduction reactions multiplying an equation by a constant factor does not change the value of E not 2. in a galvanic cell; E not of the cell is equal to E not of cathode minus E not of the anode 3. half cell with smaller E does not constitute anode and half cell with larger E does not constitute the cathode For example in a Daniel cell, E not for Zn 2 plus to Zn is equal to minus 0.76 volts and E not for Cu 2 plus to Cu is equal to 0.34 volt Therefore we know that Zinc electrode will act as anode and copper electrode as cathode and E, not the cell is equal to E, not cathode minus E, not anode which is equal to 1.10 volt 4. smaller the value of E not, stronger is the reducing agent And larger the value of E not, stronger is the oxidizing agent Thanks for watching Download Extraclass.com app: - Play Store: http://bit.ly/extraclassapp Follow us on our social media handles to stay updated.
