The LOL Charts Concept Builder provides students with a rigorous exercise in conducting an energy analysis in order to construct a bar chart that demonstrates how energy is stored, transferred, and/or conserved by a system undergoing a change between two states of motion.
Potential Energy Diagrams Practice Name:_____ 1. Which letter (a–f) represents potential energy (ΔH) of the products? _____ 2. Which letter (a-f) represents potential energy (ΔH) of the activated complex? _____ 3. Which letter (a-f) represents potential energy (ΔH) of the reactants? _____ 4.
A potential energy diagram, also known as a reaction progress curve, is a visual representation of the energy changes that take place during a chemical reaction. A diagram of potential energy illustrates how a system's potential energy changes as reactants are converted into products.
1. Show your choice of system in the energy flow diagram, unless it is specified for you. **Always include the earth in your system. 2. Decide if your system is frictionless or not, and state this. 3. Sketch an energy bar graph for the initial situation. 4. Complete the analysis by showing energy transfers and the final energy bar graph. 1.
1. Draw an energy pie chart for each scenario A and B. 2. List objects in the system within the circle. **Always include the earth’s gravitational field in your system. 3. On the physical diagram, indicate your choice of zero height for measuring gravitational energy. 4.
Energy Ws #1: Reaction Rates 1. Chemical reactions occur when reactants collide. For what reasons may a collision fail to produce a chemical reaction? 2. If every collision between reactants lead to a reaction, what determines the rate at which the reaction occurs? 3. What is the activation energy of a reaction, and how is this energy related ...
