catalyst ............. a) changes the mechanism for a reaction b) slows down the rate of a reaction c) changes the free energy change of a reaction d) is included in the balanced chemical equation for a reaction

All chemical reactions that are used as fuel must... O Have products higher in energy than reactants. O Have products lower in energy than réactant. O Have products with the same energy as the reactants.

Use energy diagrams to compare catalyzed and ucatalyzed reactions

at of Reaction The heat of reaction, AH, is the amount of heat absorbed or released uring a chemical reaction. It is calculated as the difference in energy of the products and the reactants. gure Energy diagram B Progress of reaction Type here to search D < 1 of 1 O II CD Label the energy diagram (Eigure 1) by matching each term to the appropriate letter from the graph.
