During a chemical reaction, a fixed amount of Iron combines completely with a fixed amount of oxygen to form Iron oxide. Which statement best describes the mass of the iron odide that is
produced?
a)The mass is equal to the mass of the Iron minus the mass of the oxygen before reacting.
B)The mass is equal to the mass of the Iron plus the mass of the oxygen.
C)The mass is greater than the combined mass of both the Iron and the oxygen
D)The mass is less than the mass of the Iron but greater than the mass of the oxygen before reacting.

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
