the rate of the forward reactions is equal to the rate of the backward reaction
not stopped but forward and backward reaction are constant
Just the temperature change it
how far does the reaction take place
Le Chatelier's principle
At equilibrium when subjected to a change will respond in such a way to minimize the effect of the change
Increase reactants , equilibrium move to the right
Change in volume or pressure will affect the equilibrium if the involves change in gas molecule
Increase move the equilibrium to the side of less less volume
darker - ligther
taking away heat equilibrium moves to rights, to form more products.
Mixture becomes light
Temp increase concentration decrease therefore k decrease
Do not change the position of the equilibrium or the yireld but equilibrium is archive quickly
Equilibrium Vapor Pressure
pressure exerted by a vapor on its liquid when the rate of condensation is equal to the rate of evaporation
Factors vapor pressure
Nature of the substance
Evaporation is a surface phenomenon and occurs at a range of temperature.
boiling is a volume phenomenon ans occurs at a specific temperature, determined by the nature of the substance and the outside pressure
Is exerted by the particles in the vapor phase.
Vapor pressure equal to the external pressure
Enthalpy of vaporization
Energy required to convert one mole of a substance in its liquid state into one mole of gas
