The equilibrium constant shows how far the reaction will progress at a specific temperature by determining the ratio of products to reactions using equilibrium concentrations. Here is how you would classify the phase changes as endothermic or exothermic: melting, evaporation and sublimation are endothermic processes while freezing, condensation and deposition are exothermic processes. When moving from a more ordered state to a less ordered state, energy input is required. An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water.

The graph below charts the energy change when a candle burns. The wax (C 34 H 70) combusts in the presence of oxygen (O 2) to yield carbon dioxide (CO 2) and water (H 2 O). Because more energy is released when the products are formed than is used to break up the reactants, this reaction is exothermic, and ΔH for the reaction is negative.

In the investigation on exothermic and endothermic reactions learners work with concentrated sulfuric acid. They must work in a well ventilated room or, if possible, in a fume cupboard. An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light. These reactions are the opposite of endothermic reactions and can be expressed in a chemical equation as follows: Reactants → Products + Energy In both graphs, the x axis should indicate progress of a reaction and the y axis should indicate the energy of a reaction. In an exothermic graph, the products are at a lower energy level than the reactants, because energy is released. Exothermic reactions: vinegar and baking soda, vinegar and steel wool, hydrogen peroxide and dry yeast, acetone and Styrofoam. Graph your results!
