An electrochemical cell is formed by the combination of Zn and Ag . For this cell H=-n F E_ cell Here H = Enthalpy change E _ cell =e . m . f of the cell that is 1.1 V Select the correct statement(s) about this cell

Options

  1. AEntropy change of the cell reaction is zero
  2. BTemperature coefficient of the cell is zero
  3. CG is negative for the cell reaction
  4. DEntropy change of the cell reaction is non-zero

Correct answer

C. G is negative for the cell reaction

Step-by-step solution

S = nF ( E _ cell ~T )_ P G =- nFE _ cell = H - T ~S If H=-n F E_ cell , it means S=0
