Chapter 7 - Reversible Reactions and Chemical Equilibrium

Catalyst

________ does not affect the position of equilibrium, only affects the time.

temperature shifts

An increase in ________ the equilibrium to the left, forming more reactants.

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.

reverse direction

Positive: reaction favorable in ________ only Chapter 7.3 The equilibrium constant.

Kc

________: uses concentrated values when concentration is at equilibrium.

K

________ ≈ 1, there are approximately equal concentrations of reactants and products at equilibrium.

Equilibrium

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

Free energy

________: available energy; useful work obtained from reaction.

Reaction quotient

________, Qc: expression that is identical to equilibrium constant expression, but concentration not necessarily at equilibrium.

temperature shifts

An increase in ________ the equilibrium to the right, forming more products.

Equilibrium constant

________ keq or kc: forward rate constant divided by the reverse rate constant.
