3 cards from this section. Quick, good the night before a test.
Define reversible reaction.
Focus on how products relate to reactants.
What does dynamic equilibrium mean?
Think of it as balance.
What does dynamic equilibrium refer to?
Focus on the 'dynamic' aspect of equilibrium.
Le Chatelier's Principle states that:
Think about how changes affect reactions.
Given the reaction N2 + 3H2 ⇌ 2NH3, if 0.9 moles of NH3 are produced in a 1-liter container and the initial moles of N2 and H2 were 1.5 and 4.5 respectively, calculate the equilibrium concentrations of all species.
Think about how much each species changes at equilibrium.
If the equilibrium constant K for A + B ⇌ C is 5.0 at a certain temperature, and if the initial concentrations are [A] = 1 M and [B] = 1 M, what will be the equilibrium concentrations?
Use algebra to express the changes in terms of x.
