Ch.17 Kinetics & Ch. 13 Equilibrium

Kinetics

The study of rates of reactions

Collision Theory

Explains whether a collision will result in a reaction or not. It says that for a reaction to occur molecules of A must collide with colecules of B with the right correct orientation and enough energy

Molecular Orientation

The collision must have the correct orientation for the reaction to go

Activation Energy

The amount of energy needed to get a reaction to go

Reaction Coordinates

A graph demonstrating reactants on the left and products on the right, showing the amount of activation energy needed

How is the rate of a reaction measureed?

By the change in concentration of a reactant or product over time

What are the 5 factors that change the rate of a reaction?

Concentration, Surface Area, Pressure of Gas Reactants, Temperature, and a Catalyst

Chemical Equilibrium

The forward reaction and the reverse reaction both occur at the same rate, being dynamic because it doesn’t stop. It has equal rates and unchanging concentrations, so not equal products and reactions

Concentrations at equilibrium
