# Activation energy diagram worksheet

Reaction Coordinate Diagrams. The diagram shows the energy of the reactants and products (and, therefore, E). The high point on the diagram is the transition state. The species present at the transition state is called the activated complex. The energy gap between the reactants and the activated complex is the activation energy barrier. Energy Diagrams Activation energy is the energy a reaction needs to get started. At the bottom of the page are two energy diagrams—one for an exothermic reaction and one for an endothermic reaction. Follow the directions below to label the energy diagrams. 1. In an exothermic reaction, the chemical energy of the reactants is greater than The activation energy of a chemical reaction is the energy required to initiate collisions energetic enough to allow the transformation of reactants to products and is described by the Arrhenius equation. R E a k Ae where: k = rate law constant A = frequency factor R = universal gas constant, 8.314J/ mol•K E a = activation energy of the reaction Energy can be a reactant or byproduct of any reaction. While all reactions require some amount of energy to get going, called the activation energy, whether the reaction is endothermic or exothermic depends on where energy fits into the equation. For example: Endothermic reactions: reactants + energy = products. And for Exothermic reactions: Electrical energy worksheets. Potential and kinetic energy printables.

Activation energy in chemistry is the amount of energy required to start a reaction. With this diagram, you can also calculate the energy of products, reactants, e.t.c. This is also a useful diagram to explain the function of a catalyst, something used to decrease the activation energy.CH302: Worksheet 15 on Kinetics Answer Key 1. What factors determine the rate of a reaction? How does each of them affect the rate? Answer: Rate = []xAe[-Ea/RT]. Shown in this equation, the factors affecting rate of reaction are: concentration and order of reactants and products ([]x, which increases as rate increases), the activation energy required energy and the energy of the reactants is the activation energy.

Question 1: On a potential energy diagram, the activation energy is greatest under which of the following conditions? The potential energy of the products is greater than the reactants and the change in enthalpy is positive. The potential energy of the products is less than the reactants and the change in enthalpy is positive. Another “Energy Diagram” • This is an example of a reaction that needs energy to get started. • The energy needed (a) is called the activation energy. • The reactants had 100 kJ of energy. • In the “activated complex” the chemicals had 400 kJ of energy. • After the reaction was fully
