Vapor Pressure is a form of Dynamic Equilibrium Molecules are constantly moving between phases, but the rate at which the molecules move from the liquid ↔ gas phase is constant Chemical Equilibrium a state in which the rate of a forward reaction and the rate of the reverse reaction are the same as the reaction uses its reactants the forward reaction starts to slow down How is chemical equilibrium reached? reactants and products are still forming when it is reached, just at th...

exothermic reaction : a chemical reaction that releases energy to its surroundings "Heat" is best described as : the energy transferred as a result of a temperature difference endothermic reaction : A reaction that ABSORBS energy in the form of heat Iodine Vapor depositing on a cool surface : exothermic water condensing on a cold glass : exothermic propane burning : exothermic dry ice subliming 2 | P a g e : physical, endothermic reaction water freezing : exothermic reaction W...
