Question

In the temperature range 0-90 ºC , the potential difference of the following cell:
Pt (s) | H2 (g, f = 1) | HCl (aq, m = 0.1) | AgCl (s) | Ag (s)
changes as follows with the temperature:
Ecell (V) = 0.35510 – 0.3422x10^-4t - 3.2347x10^-8t² + 6.314x10^-9t³ (t being the temperature in ºC) Write the reaction and calculate ΔG, ΔH and ΔS at 90 ºC.
Result: -34388 J/mol, 10.94 J/Kmol, -30.42 KJ/mol

Pt (s) | H2 (g, f= 1)| HCl (aq, m = 0.1)| AgCl (s) | Ag (s)
changes as follows with the temperature:
Epila (V) = 0.35510 – 0.3422x104t - 3.2347x10-82 + 6.314x10-f³ (t being the temperature
in °C)
Write the reaction and calculate AG, AH and AS at 90 °C.
Result: -34388 J/mol, 10.94 J/Kmol, -30.42 KJ/mol
