The three general rules for reaction coordinate diagrams are as follows: The number of "peaks" should be equal to the number of steps in the reaction. ... If the products are below the reactants then enthalpy change will be negative, and the reaction is exothermic. The inverse is true of endothermic reactions. You can start with a generic potential energy diagram for an exothermic reaction. A reaction is defined as exothermic if you put in less energy to break the bonds of the reactants - the is the activation energy - than it is released when the products are formed. So, the activation energy is the minimum amount of energy required for a reaction to take place. In your case, you need at least "50 ... Start studying Chem-C125 Final Exam Review. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Reaction coordinate diagrams. The intrinsic reaction coordinate (IRC), derived from the potential energy surface, is a parametric curve that connects two energy minima in the direction that traverses the minimum energy barrier (or shallowest ascent) passing through one or more saddle point(s). However, in reality if reacting species attains enough energy it may deviate from the IRC to some extent.

An energy level diagram. shows whether a reaction is exothermic. or endothermic. It shows the energy in the reactants and products , and the difference in energy between them. Exothermic reaction A reaction coordinate diagram is a graph that plots energy versus reaction progress. The amount of energy that needs to be added is called the activation energy, which is the point where the line ... Explanation: The fully filled in reaction coordinate diagram is displayed below. The arrow marked in the question represents the activation energy, which is the energy barrier that must be overcome in order for the reactants to form products. This reaction is also exothermic because the energy of the products is lower than that of the reactants. 1! Energy/Reaction Coordinate! Diagrams! Thermodynamics, Kinetics !
