Reaction Quotient Units

[Juliana Chopelas 1A]

Does the reaction quotient "Q" have a specific unit if one is not listed or mentioned in a problem?

Usually we will assume the units for concentrations will be in mol/L if not stated, and the ratio of that cancels out the units. Therefore the reactant quotient is unitless.

You can determine the units by what will cancel out and if not than it can be unitless.

[Ashley Wang 4G]

Since Q is calculated the same way as K, and is a ratio, it does not have units. However, as with K, we have to make sure the values we're plugging in are in terms of units taken by Q (eg. mol/L and not mmol/L for Qc).

[McKenna_4A]

Q is a ratio, therefore it doesn't have units, just like K.

[Amanda Lin 2I]

Q is calculated like K and is a ratio, so it would be not have units.

Q will also be unitless since it is calculated the same way as K. Just make sure you are using the correct units for molarity.

[BCaballero_4F]

Q does not have specific units because it is a ratio.

[Eunice Nguyen 4I]

Normally, whether or not it is mentioned in the problem, Q is unitless.

[Jasmine Vallarta 2L]

like K, Q is also unitless

[Caroline Zepecki]

The reaction quotient is unitless because the units cancel out.
