Spontaneous and Non-Spontaneous Reactions
Chemical reactions can be classified into two categories: spontaneous and non-spontaneous reactions. Here are the differences between these two types of reactions:
Spontaneous Reactions
Spontaneous reactions are those that occur naturally, without external intervention, and are favored by the available free energy in the system.
Spontaneous reactions have a negative free energy, which means that the total energy of the system decreases during the reaction.
Examples of spontaneous reactions: combustion of a fuel, the reaction between oxygen and carbon to form carbon dioxide and water.
Non-Spontaneous Reactions ❄️
Non-spontaneous reactions are those that do not occur naturally and require additional energy to occur.
Non-spontaneous reactions have a positive free ene
