A potential energy surface (PES) describes the energy of a system, especially a collection of atoms, in terms of certain parameters, normally the positions of the atoms.

1 Explain how the mixing of reactants and products affects the position of chemical equilibrium.text develops, most contributions to the potential energy that we need to consider in chemistry are due to this Coulombic interaction. World of Chemistry Text Pages: p.320-326, 334-336, 596 When chemical reactions occur, there is also a heat energy change that can often be detected as a temperature change.Endothermic Reactions the reactants have less potential energy than do the products. Throughout Chem 343,344, and 345, potential energy surfaces will be commonly used to explain a variety of chemical concepts.Typically, the reactant or reactants start on the left side of the PES and move towards products on the right side moving along the reaction coordinate. In an energy diagram, the reactants are at a higher potential energy compared to the products. How would you describe this reaction?Videos on topic View all (5).
