066 - Le Chatelier's Principle
In this video Paul Andersen explains how Le Chatelier's Principle can be used to predict the effect of disturbances to equilibrium. When a reversible reaction is at equilibrium disturbances (in concentration, temperature, pressure, etc.) will be offset to reach a new equilibrium. For examples when more reactants are added the reaction will move to the right to reestablish the equilibrium constant.

This goes hand in hand with the fact that when enthalpy is endothermic (delta H is greater than 0), then when it has a lot of temp it’s spontaneous (goes to the right) and when it lowers temp, it goes to the left is non spontaneous.

In any reaction where it is reversible and we have reactant and products and equilibrium is reached, if there is ever a stress factor involved like increase/ decrease temperature, increase/ decrease pressure there is going to be a new equilibrium will be established. Increasing yield by concentration when we want more product we raise the concentration of the reactants to shift reaction towards the right and vice versa.

Hey Great video however, with the reaction of N2O4 to 2NO2 when you increase pressure or decrease volume why would the reaction shift right first and then go to the side of fewer moles? I thought that it would shift left to reactants first and stay there till the volume would allow the product of nitrogen dioxide to form? A little confused

@maxnguyen3503 4 жыл бұрын

Great vid sir! Just a little comment. If you're taking a test and it doesn't give you the energy flow (positive or negative) then what Mr Anderson was using there is called enthalpy. So basically, for the reversible process of turning hydrogen and nitrogen gas into ammonia, on the forward reactants side, there are 4 mol of gas while on the forward products side, there are only two, so during the process heat was released. Also, catalyst doesn't shift the equilibrium. With a one way reaction, it helps making the reaction go to completion faster. But, in a two way reaction, it makes the reaction reach equilibrium more quickly.

When more of a reactant or is added, will the new equilibrium have a different Kc (equilibrium constant) than our original reaction? Or will it remain constant?

@dae1925 3 жыл бұрын

Kc depends on Temperature

@LuZ-rd5yl 4 жыл бұрын

After we place a stress on the reaction (by removing/adding reactants) and allowing that reaction to come to a new equilibrium, does the new equilibrium still have the same equilibrium constant? Afterall, it is referring to the same chemical equation.

@HanTran-yi4sb 4 жыл бұрын

Yes, since for a given reaction, at a temperature, Kc stays the same. The only thing that changes is Q. When the equilibrium is thrown off, the value of Q will change (in other words, Q no longer equals to Kc). According to Le Chatelier's principle, the reaction will shift in the direction that restore the equation: Q = Kc.
