1. Reaction Rates Main Concept:
The rate of a reaction is influenced by the concentration or pressure of reactants, the phase of the reactants and products, and environmental factors such as temperature and solvent.

2. Reaction Rates Measuring Reaction Rates
Factors that Affect Reaction Rates

3. - The rate of reaction is measured by the amount of reactants converted to products per unit of time.
Ex. concentration or volume or mol
time time time

4. - A variety of means exist to experimentally measure the loss of reactants or increase of products as a function of time
- One important method involves the spectroscopic determination of concentration through Beer’s law

5. - The rate of a reaction is influenced by reactant concentration (except in zero-order processes), temperature, surface area, and other environmental factors.

6. - The rate of a reaction is influenced by reactant concentration (except in zero-order processes), temperature, surface area, and other environmental factors.
- Reasons for this are due to collision theory:
- reactants must collide
- reactants must collide with sufficient energy
- reactants must collide with correct orientation
- Higher reactant concentrations, higher temperatures, and greater surface area increase chances of proper collisions
