# In Some Reactions - A + B ⇌ C + D - Reaction can go forward and backword - In a sealed container, a dynamic equilibrium can be reached: - Forward and backward reactions are both happening at the same rate - Concentrations of reactants and products are constant - Catalysts have no effect on position of equilibrium # A System Will Always Shift the Position of Equilibrium to Oppose a Change - e.g. If we increase the temperature, it will shift to decrease the temperature. - **Section 20 - Reversible Reactions** - **Examples:** - N2 + 3H2 ⇌ 2NH3 - CuSO4 + 5H2O ⇌ CuSO4.5H2O # How Will the Position Change? - **Increase temp** - Shift in the endothermic direction - **Decrease temp** - Shift in the exothermic direction - **Increase pressure** - Shift to the side with fewest molecules - **Decrease pressure** - Shift to the side with most molecules. # *Do Not Confuse* - Rate + Position of Equilibrium
