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.
Which 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.)

Classify each statement about catalysts as true or false. 1. Biological catalysts are known as enzymes. 2. A catalyst is chemically unaltered during the chemical reaction and therefore is reused over and over again in a reaction. 3. A catalyst lowers the activation energy for a reaction. 4. A catalyst is always used in high concentration. 5. A catalyst speeds up the rate of a reaction.
