chemical thermodynamics
study of relationship between chemical reactions and the laws of thermodynamics
first law of thermodynamics
relates energy gained by a system to the energy lost by its surroundings
exothermic
energy is released
endothermic
energy is absorbed
second law of thermodynamics
every chemical reaction causes a decrease in usable energy and an increase in entropy
spontaneous
reaction that occurs without continuing outside help
chemical kinetics
deals with rates of chemical reactions
activation energy
kinetic energy that’s necessary for molecules to react
catalyst
alters the rate of a chemical reaction without being permanently changed by the reaction
reversible
reaction that proceeds either direction
chemical equilibrium
two reactions in opposite directions occur at the same rate with no change
le chatelier’s principle
system at equilibrium is disturbed, the system will react to partially offset the disturbance
