K units

[Donna Nguyen 2L]

Why are units omitted when calculating K?

[Hui Qiao Wu 1I]

Explaining in a non-chemistry way, K is the ratio of products over reactants. And ratios are just numbers; they don't have units.

[Eunice Nguyen 4I]

K is a unitless quantity, because it's just a ratio of product over reactants. This also goes into the concept of activities (but that hasn't been really gone over in depth yet)

[Justin Sarquiz 2F]

The equilibrium constant is actually the activity of the product divided by the activity of the reactant. Calculating the activity is its own separate equation, but in that equation the units actually cancel. Therefore, the activity of the products and reactants have no units making K have no units too.

K is a constant

[Christine Honda 2I]

For the purpose of this class, K is unitless. But in higher classes, it refers to the "activity" of the reactants and products.

[BritneyP- 2c]

When you are looking for K is is molarity over molarity, which can cancel out all units. And if it doesn't cancel out all units, imagine the reactants changing to products or products changing to reactancts as activity, and activity is unitless.

[Rohit Ghosh 4F]

K is simply a ratio not a unit of measure

[Jasmine Fendi 1D]

K actually measures the activity of the reaction. For this class, I think we omit the units for simplicity

[AngieGarcia_4F]

I think it's because K is an activity and activities don't have units.

K is just a number that is used to show the ratio of products to reactants. I dont think K is ever used in equations so it doesnt need units anyways
