Rate of Reaction and Rate Law
How to measure and express the speed of a chemical reaction.
Rate of Reaction
The rate of reaction is the change in concentration of a reactant or product per unit time — it can be an average rate or an instantaneous rate.
Factors Affecting Rate
Concentration, temperature, and the presence of a catalyst all influence how fast a reaction proceeds.
Order and Molecularity
Order is an experimentally determined value from the rate law; molecularity is the number of reacting species colliding in an elementary step.
