Reaction constant

Postby Rucha Kulkarni 2A » Sun Nov 26, 2017 11:10 pm

For a particular reaction, if it isn't specified whether the constant is Kc or Kp do we just assume that they mean Kc?

I believe they will always specify because we would need to be given other values in order to solve for Kp or Kc. However I think it is more common to have Kc in a problem.

I'm pretty sure Lavelle said they would just call it K without specifying, but you should know by the values given in the problem as p has to do with pressure and c with molarity.

the problem will usually call it just K, and depending on what other values they give you in the problem, those will determine whether it is referring to Kc and Kp. The importance i think is to know the difference between the two.

Generally, Kc is used for (aq) and Kp is used for gases.
