s. Reactions are favorable when they result in a decrease in enthalpy and an increase in entropy of the system. ... A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring.

Is favorable spontaneous?

Reactions are favorable when they result in a decrease in the enthalpy and an increase in the entropy of the system. When both of these conditions are met, the reaction is said to be spontaneous at all temperatures.

Is spontaneous the same as thermodynamically favorable?

A "thermodynamically favored" reaction (ΔG < 0) is sometimes referred to as "spontaneous". ... If a reaction's ΔH is negative, and ΔS is positive, the reaction is always thermodynamically favored. If a reaction's ΔH is positive, and ΔS is negative, the reaction is always thermodynamically disfavored.
