Units for K

[Alexis Robles 2k]

So we do not use units for K? Can someone explain this to me?

[Tiffany Chao 2H]

No because K is a constant. We use brackets around equilibrium concentration. The brackets indicate molar concentration so we omit actual units.

[Jasleen Kahlon]

K is representative of a ratio, products/reactants. It is used to compare rates of reaction and therefore does not have units.

[chrisleung-2J]

Neither K nor Q have units

[William Chan 1D]

K doesn't have units technically because they all cancel out, and it comes out to be just a number ratio.

Equilibrium constants have no units; this is because it is a ratio of similar quantities.

[TanveerDhaliwal3G]

K doesn't have units because it is a ratio of molar concentrations.

[CalvinTNguyen2D]

K does not have any units associated with it, since it's just a ratio of different molecules and species.

[SVajragiri_1C]

K is a constant because when calculating it all the units cancel out, so there is no unit for it.

[kendal mccarthy]

K is a constant, meaning there are no units used. But, it is a good way to check your work if you end up with units because there should not be any because they should all cancel out.

[Eesha Chattopadhyay 2K]

In class, Dr. Lavelle mentioned briefly saying that technically K is the ratio if the activities of the products and reactants, which is unit-less.

[Morgan Carrington 2H]

Since K is a ratio of values with the same units, they cancel out and are not present in the K value. I would still include them in the K expression to show my work though!

[SVajragiri_1C]

There is no unit for K, it is a constant for equilibrium. You can prove this because when you solve for K, all the units cancel out.

[Veronica Lu 2H]

There are no units since K is more so a ratio

[Angela Wu-2H]

K has no units because of "activity"; however, activity is really low (close to 1) for the most part, so the equation ratio is simplified to the form that we know. But also, in the ratio, the units in the numerator and denominator will cancel out.

[Mitchell Koss 4G]

K has no units but units you plug in matter, so use mol/L not mL or mol.

[105335337]

K has no units as hen you do all the calculations, the units cancel out. Furthermore, this is because K is just a constant.

[pmokh14B]

K does not have units it is a constant.

[Kallista McCarty 1C]

Since K is a constant it does not have units associated with it!

[Jainam Shah 4I]

K does not have units. The brackets signify its molarity or concentration of a reactant or product. As Dr. Lavelle discussed in class the true way to explain is via the ratio of the activities of the reactants and product. K is simply giving us the relative information of the rates and which reaction is favored. Activities don't have units and the expression we write assumes the activities are close to 1.

[805422680]

K does not have units as it is a constant value of the ratio of concentrations of products to reactants.

[Celine 1F]

K, a constant, demonstrates the ratio of products and reactants so it does not have units
