The reaction of NO gas with H2 gas has the following rate law: Rate = k[H2][NO]2 A proposed mechanism is: Step 1: H2 (g) + 2 NO (g) → N2O (g) + H2O (g) Step 2: N2O (g) + H2 (g) → N2 (g) + H2O (g) What is the molecularity is step 1? What is the molecularity in step 2? Which step is the rate-determining step?

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...
