Chemical Equilibrium and Chemical Kinetics Flashcards
State of a system in which the concentration of the reactant and the concentration of the products do not change with time.
Chemical Equilibrium
Achieved when the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant.
Chemical Equilibrium
Is one in which all species are present in the same phase.
Homogeneous Equilibrium
Is one in which species exist in more than one phase.
Heterogeneous Equilibrium
“If external stress is applied to a system at equilibrium, the system ADJUST to partially offset the stress as the system reaches new equilibrium.”
Le Chateliers Principle
Factors affecting Chemical Equilibrium
Concentration, Temperature and Pressure/Volume
Study of the rate of chemical reaction
Chemical Kinetics
Change in the concentration of a reactant or a product with time (M/s)
Reaction Rate
“states that the rate of a chemical reaction is proportional to the number of collisions between reactant molecules. The more often reactant molecules collide, the more often they react with one another, and the faster the reaction rate.”
Collision Theory
Factors Affecting Reaction Rate
Concentration, Surface Area, Temperature and Catalyst
