11. For GE, the EMF values are known at two temperatures. The activity of the electrolyte solution is equal to unity.
1. Write down the reaction equations on the electrodes and the final reaction in the GE
2. Determine the temperature coefficient of the emf.
3. Calculate the EMF value at a temperature of 298 K, compare it with the reference value.
4. Calculate the values of the standard molar enthalpy, entropy, Gibbs energy of the final reaction occurring in this GE at 298 K, compare them with the values obtained from the thermodynamic characteristics
Zn|ZnCl2|H2Cl2 solids, Hg | Zn
E1, mV E2, mV T1, K T2, K
