Activity 5: Spontaneity and Gibbs' Free Energy Directions: Calculate AG°, AHº, AS° then predict whether the reaction is spontaneous. Consider the following reaction: N2(g) + 3H2(g) –→ 2NH3(g) 1. AH = - 92.4 kJ/mol (a) The absolute entropy values, S, at 238 K for N2(g), H2(g) and NH3(g) are 192 J/Kmol, 131 J/Kmol and 193 J/Kmol respectively. Calculate AS° for the reaction and explain the sign of ASº. (b) Calculate AG° for the reaction at 238 K. State and explain whether the reaction is spontaneous.
