Question

suis reaction progress (x axis) for a typical 4. Sketch a plot of energy Swatch a plot of energy (y axis) versus reaction progress xaxis for on Then, draw another line onto the same plot which shows how the draw when the reaction occurs in the presence of a catalyst. Label each line chemical reaction in terms of the meaning in how a catalyst increases the rate or a chemical reaction in terms of the Explain how a cada of your plot exothermic reaction. Then, draw a curve changes when the reaction occurs CCESSEISTITIS 5. Consider the reaction in Exercise 4: 3. Would this reaction favor formation of mostly products or mostly reactants? b. Would the equilibrium constant, K , for this reaction be less than, equal to, or greater than 1? Circle one, and explain your choice. C. When this reaction has reached equilibrium, would the forward rate be less than, equal to, or greater than the reverse rate? Circle one, and explain your choice. 6. The burning of a piece of paper in air (to produce co, and H,O vapor) is a spontaneous exothermic reaction. a. What would be necessary to start this reaction? b. After the reaction starts, what provides the activation energy for the reaction to continue? 7. Read the assigned pages in your textbook and work the assigned problems. CA25 -124-

-- I without Catalyst Activation Erergy without catalys y activation Energy with Catalyst Energy Reactant ---> product T Rem → since activation tinat eneron energy o decreases on adding catalyst; therefore note of reaction increases draffically
