Concept #1: Introduction to Reaction Orders

Practice: The rate law for an elementary and/or nonelementary reaction is _________________________:

Concept #2: Zero-Order Reactions

Example #1: Zero Order Kinetics: Does increasing the # of cars also increase the rate that the cars cross the 1-lane bridge?

Concept #3: 1st Order Reactions

Concept #4: 2nd Order Reactions

Practice: What is the overall reaction order for the following rate law? v = k [A] 1 [B]1 [C]0

Concept #5: Pseudo 1st Order Reactions

Practice: Which of the following options is true for a reaction with the provided rate law: v = k [NO]2 [O2]

Practice: Consider the nonenzymatic elementary reaction from A → B. When the initial [A] = 20 mM, the reaction velocity is measured as 5 μM/min. Determine the reaction order and calculate the rate constant for the reaction.

Practice: Consider the nonenzymatic elementary reaction A  B.  When the [A] = 20 mM, the reaction velocity is measured as 5 µM of “B” produced per minute.  Calculate the rate constant for the reaction. Hint: Consider the rate law.

Practice: The hypothetical elementary reaction 2A --> B + C has a rate constant of 10-6 M-1s-1.  What is the reaction velocity when the concentration of A is 10 mM?
