Kinetics and Equilibrium vocabulary

Potential energy diagram

• the rate factor

• The speed of light

• a graphical expression of the energy changes during a reaction

• The coefficient of friction

Forward Reaction

• A reaction that proceeds from left to right

• A reaction that proceeds from right to left

• A reaction that proceeds in both directions

• A reaction that proceeds from the center

Double Arrow

• Indicates a reaction that is not reversible

• Indicates a reaction that is exothermic

• Indicates a reaction that is endothermic

• Indicates a reaction that goes to equilibrium, not completion

Reverse Reaction

• a reaction that proceeds from left to right

• a reaction that proceeds from right to left

• a reaction that proceeds from top to bottom

• a reaction that proceeds from bottom to top

Reversible Reaction

• A reaction that produces a gas

• A reaction that involves a catalyst

• A reaction that can happen in the forward or reverse direction

• A reaction that produces a solid

equilibrium

• Term that describes when the concentration of products and reactants in a chemical reaction become constant

• A state of balance between opposing forces

• A reaction that occurs when two or more substances interact

• A type of reaction in which energy is absorbed

Phase Equilibrium

• A situation where two substances are mixed together

• A situation where two forces are balanced

• A situation where two particles collide

• a situation where two phases are present at the same time

Solution Equilibrium

• Describes the reaction rate of a chemical reaction

• describes particle movement in a saturated solution

• Describes the rate of change of a system

• Describes the amount of energy in a system

LeChatelier's Principle

• A system at equilibrium will remain unchanged under stress

• A system at equilibrium will become more stable under stress

• A system at equilibrium will become less stable under stress

• A system at equilibrium will shift under stress to establish a new equilibrium

Unsaturated solution

• a solution that has reached its maximum solubility

• an aqueous solution that has a low concentration of solut

• an aqueous solution capable of dissolving additional solute

• a solution that has a high concentration of solute
