Consider the reaction:
NH3 (g) + HCI (g)
NH4CI (s)
Given the following table of thermodynamic data,
Substance AHf (kJ/mol) S° (J/mol - K)
NH 3 (g)
HCI (g)
NH4C1 (s) -314.4
-46.19
192.5
-92 30
186.69
94.6
determine the temperature (in °C) above which the reaction is nonspontaneous.
This reaction is spontaneous at all temperatures.
