IB Chemistry Topic 5 & 15 Definitions
The minimum collision energy required for successful collision, dependent on a particle's kinetic energy
A substance that increases rate without changing itself by providing an area for reactants to come into proper orientation to lower the activation energy
A reaction environment that conserves mass and energy. This means no reactants or products can exit into the surroundings.
Mass or moles per unit volume, expressed as g/dm3 or mol/dm3
Mass per unit volume of pure substance, expressed as g/dm3
A state of a closed system wherein the rates of the forward and reverse reactions are equal, maintaing the concentratino of products and reactants
A state of a closed system when the concentration of products and reactants remains constant
The state of all forces on an object being balanced and cancelling out to zero
The actual amount of product formed during the experiment
The reactant that produces the least product according to the molar ratio
The maximum amount of product that can be created
A reaction that can only occur forwards to convert reactants to products
The effect a reactant's concentration has on the rate of the reaction
The sum of the orders of all the reactants in the rate
The percentage of the theoretically maximum yield that is experimentally produced
An equilibrium between phase changes for example between liquid and gas. The overall concentration of products and reactants remains the same.
Measure of the change in concentration over change in time
A reaction that can occur forwards to convert reactants to products and reverse to convert products to reactants
A substance used to form a solution by being dissolved by a solvent
A mixture of a solute dissolved in a solvent
A substance used to form a solution by dissolving a solute
The ease with which a reaction occurs
A solution with a known concentration
The predicted amount of product formed in the equation
