For the chemical reaction: A + B 3 C observed to have a rate law of Rate = k [B]2, the following reaction mechanism has been proposed. 2 B D (slow) D + A 3 C + B In your evaluation of the reaction mechanism you would conclude the mechanism is: A) a plausible representation of the reaction B) an implausible representation as the predicted rate law does not match the observed rate law C) an implausible...
36. Many biochemical enzyme reactions fit the form of Michaelis Menton Kinetics. These reactions have the following characteristics: a) the rate of reaction is proportional to the enzyme concentration, E. b) at low substrate concentration the rate is proportional to the substrate concentration, S. c) at high substrate concentration the rate is independent of the substrate concentration, S. This type of reaction rate has the form - SE Ky + S When carried out in a batch reactor a material...
