Chemical Principles: The Quest for Insight
- List two ways that enzyme catalysis of a reaction is superior to normal conditions.arrow_forward. Account for the increase in reaction rate brought about by a catalyst.arrow_forwardIn each of the following, which reaction mechanism assumption is apparently being violated? Explain your answers. a. A reaction takes place more rapidly when the concentration of reactants is decreased. b. A reaction takes place more rapidly when the reaction mixture is cooled. c. The reaction rate of A+BAB increases as the concentration of A is increased but does not change as the concentration of B is increased.arrow_forward
- Consider a reaction in which E a=129 kJ and H=29 kJ. In the presence of a catalyst, the activation energy is 48% of the uncatalyzed reaction. Follow the directions in Question 71 in drawing an energy diagram.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_forwardWhich of the reactions in Question 62 would (a) occur fastest? (b) occur slowest? (Assume equal temperatures, equal concentrations, equal frequency factors, and the same rate law for all reactions.)arrow_forward
