What can be concluded about the reaction represented below in terms of spontaneity?
#2A + B ->2C#
#DeltaH =89 (kJ)/(mol)#
#DeltaS = 0.070 (kJ)/(mol)#
1 Answer
The reaction is not spontaneous below 1000 °C, at equilibrium at 1000 °C, and spontaneous above 1000 °C.
Explanation:
A reaction is
- spontaneous if
#ΔG < 0# - at equilibrium if
#ΔG = 0# - not spontaneous if
#ΔG > 0#
At low temperatures, the
At high temperatures, the
At equilibrium,
The reaction is at equilibrium at 1000 °C.
