As a manufacturer…. . What is important in Chemistry? Thermodynamics (Energetics) tells you whether a reaction is possible Kinetics (Rates of reaction) tells you how long it takes Equilibrium tells you the extent of the reaction

Introduction: Thermodynamics is the study of heat energy changes and other related quantities which occur during physical and chemical changes. A spontaneous change , once begun, continues on its own with no further outside assistance. Thermodynamics is able to tell us whether a change is spontaneous or not - if we consider all of the possible factors which affect spontaneity. The heat energy content change is called the enthalpy change of a reaction. Exothermic reactions, where ΔH is negative, occur more frequently than endothermic ones and so appear to be more favoured.
