What are the steps to set up an ICE table?
1. Write out the balanced equation. 2. Set up the ICE table with initial concentrations. 3. Use the change in concentration based on reaction stoichiometry. 4. Use the equilibrium constant expression to solve for x, and calculate equilibrium concentrations.
What is equilibrium?
The state where the rate of the forward reaction equals the rate of the reverse reaction.
What is the equilibrium constant (K)?
A numerical value that describes the ratio of products to reactants at equilibrium for a given reaction at a specific temperature.
What is the reaction quotient (Q)?
A measure of the relative amount of products and reactants present in a reaction at any given time. Used to predict the direction a reaction will shift to reach equilibrium.
What is Le Chรขtelier's Principle?
If a system at equilibrium is subjected to a change, the system will adjust itself to counteract the change to reestablish a new equilibrium.
What is the solubility product (Ksp)?
The equilibrium constant for the dissolution of a solid ionic compound in a solution.
What is molar solubility?
The concentration of the metal cation in a saturated solution. It represents the extent to which a solid dissolves in a solution, usually expressed in mol/L.
What happens to the equilibrium when you increase the concentration of a reactant?
The equilibrium shifts towards the products to consume the added reactant.
What happens to the equilibrium constant (K) when you reverse a reaction?
The new equilibrium constant becomes the inverse of the original (1/K).
What happens to the solubility of a sparingly soluble salt when a common ion is added?
The solubility of the salt decreases (Common Ion Effect).
What happens to the equilibrium of an exothermic reaction when temperature is increased?
The equilibrium shifts towards the reactants.
What happens to Gibbs Free Energy at equilibrium?
ฮG = 0.
