Question

List the four factors studied in this experiment that can affect the rate of a chemical reaction. Nature of the reactants Temperature of the chemical system Presence of a catalyst Concentration of the reactants From Question 1, identify the factor that accounts for the following chemical observations. Enzymes accelerate certain biochemical reactions, but are not consumed. Rubber tires deteriorate more rapidly in smog-laden urban areas than in rural areas. Meat spoils more rapidly when it is not refrigerated. Gold and silver are used for jewelry, but iron and sodium (also shiny, lustrous metals) are not. Aquatic life grows more rapidly near the cooling water outfall from a power plant. Assuming that the rate of a chemical reaction doubles for every 10 degree C temperature increase, by what factor would a chemical reaction increase if the temperature were increased over 40 degree C range?
