Equilibrium - ANSWER>>Occurs when rate of forward and reverse reaction are
equal

What does K equal - ANSWER>>Concentration of products over concentration of
reactants

What does reaction rates depend on? - ANSWER>>Mechanism of reaction, which
is determined by number of colliding species

What does a large K value entail? - ANSWER>>The more favorable the rate of the
forward reaction relative to the backward --> the farther the right the reaction will
go

What does a large K value NOT ensure? - ANSWER>>That it will proceed at a fast
rate. Some may be slow.

Fill in blank: When reaction A and B are initiated, rate of forward reaction is large
because _____________. - ANSWER>>A and B concentrations are large.

FIB: Backward reactions are slow because _________. - ANSWER>>C and D
concentrations are so small.

Dynamic equilibrium - ANSWER>>Forward and backward reactions continue at
equal rates

Equilibrium can be written for these 3 types of chemical processes - ANSWER>>1.
Dissociation
2. Formation of products
3. Distribution between phases ( water & non-aqueous solutions, absorption)

What are 4 types of equilibria? - ANSWER>>1. Acid-base
