All combustion reactions are exothermic reactions. During a combustion reaction, a substance burns as it combines with oxygen. When substances burn, they usually give off energy as heat and light. … The combustion of wood is an exothermic reaction that releases a lot of energy as heat and light. AreRead More →
So that means that exothermic relates to enthalpy and that spontaneity relates to Gibbs Free Energy. I think that there are some situations that an exothermic reaction is nonspontaneous, like when entropy has a negative value. So I think, in answering your question, no, they are not the same thing.Read More →
When temperature decreases, both rates (forward and reverse) decrease but the rate of the endothermic reaction decreases more! Equilbrium shifts in the exothermic direction. Is lowering temperature exothermic? An increase in the temperature of a system favors the direction of the reaction that absorbs heat, the endothermic direction. … ARead More →
