Silver chloride can be formed from metallic silver and hydrogen chloride, based on the
reaction:
2 Ag (s) + 2 HCl (g) 2 AgCl (s) + H2 (g)
The Gibbs function for the formation, at 25ºC, are the following:
For HCl(g) is -95.3 kJ mol-1 and for AgCl(s) is -109.7 kJ mol-1
a) Knowing the reaction constant K = 1.5·103 at 80 ºC, Find the average enthalpy of
reaction, considering constant in the range of 0 to 150 ºC.
b) Assuming that the gases behave ideally, find the temperature at which, 90% of HCl has
reacted at a total pressure of 0.05 atm when it reaches the equilibrium.
