Chemistry Lesson 1

Why do concentrations of products and reactants no longer change at equilibrium?

Because the RATES of the forward and reverse reactions are equal
What state is equilibrium?

Dynamic
Why is equilibrium and dynamic state?

Because reactions continue to occur, but at the same rate so that no change is observed at the macroscopic level
What does K equal
- this is products/reactants
A small value for K yields what, and favors what?

Yields little product, and favors the reactants
A large value for K reaches equilibrium with very little what, and favors what?

very little reactant remaining, and favors the products
What does K reflect?

A particular ratio of product concentrations to reactant concentrations for a reaction
K indicates what?

The extent of a reaction
At equilibrium, what = what

Q=K
Q gives the ratio of a product concentration to reactant concentration at

ANY POINT in a reaction.
Difference between K and Q

K is the ratio of product and reactants at equilibrium, Q is at any point in the reaction
Reactions go back and forth when...

Energies are similar
Overall concentrations ________ at equilibrium

Don't change
