Example: What is the temperature range in which the following reaction is spontaneous?
N2 + 3H2 → 2NH3

Example: What is the temperature range in
which the following reaction is spontaneous?
N2 + 3H2 → 2NH3
 S ̊ N2(g) = 191.5 J/mol·K
 S ̊ H2(g) = 130.6 J/mol·K
 S ̊ NH3(g) = 192.5 J/mol·K
 ΔH ̊f N2(g) = 0 kJ/mol
 ΔH ̊f H2(g) = 0 kJ/mol
 ΔH ̊f NH3(g) = -46.19 kJ/mol
