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. • Website – https://www.extraclass.com/ • Facebook - / extraclassofficial • Instagram - / extraclassofficial • Youtube - / extraclass • Twitter - / extraclass_com • Happy Learning!! • “Thanks for watching”. • #Extraclass
