Average (General) Rate is the change in the concentration of a compound over a period of time.

###### Average Rate

Concept #1: Average Rate of Reaction Example #1: Provide the expressions for rate of disappearance of reactants and rate of appearance of products for the following reaction: 2 C3H7OH (l) + 9 O2 (g) ⟶ 6 CO2 (g) + 8 H2O (g)

Example #2: Calculate the average rate of change in concentration of NO in the first 5 seconds of the reaction if the concentration dropped from 1.3 M to 1.09 M.

2 NO (g) + 2 H2 (g) ⟶ N2 (g) + 2 H2O (g)

Practice: Consider the following reaction: 2 H2O2 (aq) → 2 H2O (l) + O2 (g)

Calculate the rate of the reaction between 25 sec and 65 sec.
