Perhaps it is easier to explain an exothermic phase change using the following argument. Liquid water had to have energy put into it to become steam, and that energy is not lost. Instead, it is retained by the
For an exothermic reaction, heat is essentially a product of the reaction. In keeping with Le Chatelier's principle, if you increase the temperature you are increasing the amount of products, and so you shift the balance at equilibrium back toward reactants, meaning there will be more reactan...

but as long as a reaction involves a net reduction in temperature, the reaction is endothermic. It's possible for this to happen because a chemical reaction always proceeds in a way that increases entropy. By contrast, exothermic reactions are those which release heat. Oxidation reactions are us...

share outer shell valence electrons, a chemical (covalent) bond is formed, and they enter a lower energy state. When atoms bond, energy is released in an exothermic reaction. If the covalent bond is broken and the molecule is split apart, it requires energy input and is thereby endothermic....

What is exothermic reaction Class 10th? An exothermic reaction isa reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an ...
It is measured in joules (J) or kilojoules (kJ). A negative ΔH indicates an exothermic reaction, while a positive ΔH indicates an endothermic reaction.Chinese: 焓变 (ΔH) 是在恒压下反应中热能变化的量度。它以焦耳 (J) 或千焦 (kJ) 为单位。负的 ΔH 表示放热反应,而正的 ΔH 表示吸热...
