Chemical Principles: The Quest for Insight
- . Account for the increase in reaction rate brought about by a catalyst.arrow_forwardBy which of the following mechanisms does a catalyst operate? a. It decreases the activation energy barrier for a reaction. b. It serves as a reactant and is consumed. c. It increases the temperature of a reaction. d. It increases the concentration of reactants.arrow_forwardWhat is the role of the activated complex in a chemical reaction?arrow_forward
- Which reaction mechanism assumptions are unimportant in describing simple ionic reactions between cations and anions? Why?arrow_forwardSubstances 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?arrow_forwardWhy are enzymes important? For example, what is the importance of the enzyme carbonic anhydrase in the body?arrow_forward
- How do chemists envision reactions taking place in terms of the collision model for reactions? Give an example of a simple reaction and how you might envision the reaction’s taking place by means of a collision between the molecules.arrow_forwardWhat is the value of the equilibrium constant of a reaction if the forward rate constant was 2.8102M1s1 and the reverse rate constant was 3.6104M1s1?arrow_forwardThe direct reaction of iron(III) oxide. Fe2O3, to give iron and oxygen gas is a nonspontaneous reaction; normally, iron combines with oxygen to give rust (the oxide). Yet we do change iron(III) oxide, as iron ore, into iron metal. How is this possible? Explain.arrow_forward
