K Depends Only on Temperature
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A given reaction's equilibrium constant has one value at a given temperature and changes only if temperature changes, regardless of starting concentrations or pressure.
Show
Starting a reaction with pure reactants or with a mixture of reactants and products yields the same K at a fixed temperature.
Watch for
Adding more reactant shifts concentrations at equilibrium, but it does not change K itself.
