Concept #1: Introduction to Rate Constants

Concept #2: Types of Rate Constants

Practice: Which of the following rate constants is negligible for the initial velocity (V _{0}) of an enzyme-catalyzed reaction?

Concept #3: Rate Law: Calculating Reaction Rate (v) with Rate Constant (k)

Practice: Calculate the reaction rate for the following simple reaction if k = 1.3 x 10 ^{-1} M^{-1}s^{-1}, initial [A] = 4.0 x 10^{-3} M, and the initial [B] = 6.0 x 10 ^{-3} M (for simple reactions, assume coefficients are reaction orders):

**A + B → 2C**
