What is Equilibrium

  1. Reactions move in both directions.
  2. Equilibrium is the point at which the rate of forward reaction is equal to the rate of reverse reaction.

The Equilibrium Constant & Expression

The equilibrium expression is a ratio between the product and the reactant.

eg. for H2 + I2 <=> 2HI

The Equilibrium expression represents tre final ratio between the two:

[HI]2 / [H2][I2]

Heterogeneous Equilibrium

Effects of Temperature on Equilibrium

  1. If temperature increases the reaction will shift in the endothermic direction (taking in heat).
  2. If temperature decreases the reaction will shift in the exothermic direction.
