During a chemical reaction, energy is either released or _____. absorbed. true or false: Physical and chemical changes can be either exothermic or endothermic changes. true. true or false: In exothermic reactions, the energy required to break the bonds in the reactants is greater than the energy released as the products form. Chemistry 12 Unit 1-Reaction Kinetics Worksheet 1-2 Potential Energy Diagrams Page 1 Chemistry 12 Worksheet 1-2 - Potential Energy Diagrams USE THE POTENTIAL ENERGY DIAGRAM TO ANSWER THE QUESTIONS BELOW: 1. Is the overall reaction as shown exothermic or endothermic? _____ 2. What is the activation energy for the forward reaction?

(thermochemistry) is the study of energy flow during a chemical reaction. Thermodynamics allows you to: predict whether or not a reaction will occur (equivalent to comparing Q to K) calculate Keq from Ho and So and Temperature (In expt. 12H part C, you will do the opposite. Tell students that when the temperature of a chemical reaction decreases, the reaction is . called an . endothermic. reaction. The first part of the word, endo, means in or into and - ther mic. has to do with heat or energy. So an endothermic reaction means that more energy goes into making the reaction happen than is released by the reaction. Chapter 12: Energy and chemical change. In grade 10 learners learnt about physical and chemical changes. In this chapter learners will learn about the energy changes that occur in chemical reactions. The concepts of exothermic and endothermic reactions are introduced. Learners will also learn about activation energy. Nuclear Energy: Nuclear Binding Energy, Fission, and Fusion. Einstein discovered that matter could be converted to energy (and vice-versa). The equation that expresses this mass-energy equivalency is: E = mc2 (c = 3.00x108 m/s) or E = ( m)c2. Every process that releases energy is accompanied by an equivalent loss of mass.
