K for a Reversed Reaction
The equilibrium expression written for a reaction written in the reverse direction is the reciprocal
of the one for the forward reaction.
K' = 1/K
K' is the constant for the reverse reaction
Intermolecular Forces
Intermolecular forces are the forces of attractions that exist between
molecules in a compound. These cause the compound to exist in a certain
state of matter: solid, liquid, or gas; and affect the melting and boiling points
