Units When Calculating Equilibrium Constant

Postby Andre_Galenchik_2L » Thu Jan 24, 2019 11:59 pm

What happens to the mol/L when calculating K? For example if there are three reactants on the products side and two reactants on the reactants side with stoichiometric coefficients of 1.

K is a constant and units are not regarded in terms of equilibrium constants.

In addition, since K is equal to mol*L^-1 divided by mol*L^-1, the units will cancel out, leaving a unitless constant K.

The units will cancel out when solving for equilibrium constants since the same units are in the numerator and denominator.

Because the equilibrium constant is a ratio, the units would cancel each other out. Therefore no units are required.
