Chemical Equilibrium Review

Flashcards covering fundamental concepts of chemical equilibrium.

Equilibrium is a state in which there are no observable as time goes by.

changes

Chemical equilibrium is achieved when the rates of the and reverse reactions are equal.

forward

Homogeneous equilibrium applies to reactions in which all reacting species are in the phase.

same

When K >> 1, the equilibrium lies to the , favoring products.

right

According to Le Châtelier's principle, if the concentration of a product is , the equilibrium will shift to the left.

increased

The relationship between Kc and Kp incorporates the term , which accounts for the change in moles of gas.

Δn

For the reaction N2(g) + 3H2(g) ↔ 2NH3(g), the equilibrium constant Kc is when temperature increases in an exothermic reaction.

decreased

The concentrations of do not appear in the equilibrium constant expressions.

pure solids and pure liquids

The reaction quotient Qc is compared to Kc to determine if the system is at .

equilibrium

A catalyst does not change the constant but helps the system reach equilibrium faster.

equilibrium

A reaction can be expressed as the sum of two or more reactions; the equilibrium constant for the overall reaction is given by the of the individual constants.
