The amino acids in the active site can be involved in all of these processes, except: Binding of the substrate. Becoming part of the product of the reaction. The actual chemical mechanism for the reaction. Binding of some necessary cofactor for the reaction. All of these can be functions of the amino acids in the active site.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
