3

Le Châteliers principle

________: a dynamic equilibrium tends to respond so as to relieve the effect of any change in the conditions that affect the equilibrium.

7

Equilibrium

________: products and reactants are occurring simultaneously at the same rate.

New cards
8

Free energy

________: available energy; useful work obtained from reaction.

New cards
9

Reaction quotient
