Reaction coordinate diagrams: Two-step diagram. Label the reactant (R), product (P), intermediate (I"), and transition states (TS; and TS2), plus the axis with appropriate units/labels. 1) Break the diagram up into 2 steps. Which one is the slow step? The fast step? 2) Endothermic or exothermic? Suppose a is added to step one. Sketch the effect of this addition on the diagram. You can identify the intermediates and by remembering: Intermediates are and then Catalysts are added to a reaction (like a reactant), and are at the end. Practice: Identify the reactants, products, intermediate(s), and catalyst(s). Put a star next to the rate-determining step. Step 1 A+B AB (fastest) Step 2 C + AB → ABC Step 3 ABC + D→ ACD + B (fast) diy

Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?
The only stress (change) that also changes the value of K is a change in temperature. For an exothermic reaction, how does the equilibrium position change as temperature increases, and what happens to the value of K? Answer the same questions for an endothermic reaction. If the value of K increases with a decrease in temperature, is the reaction exothermic or endothermic? Explain.
