Kc vs Kp

[Areena H 2K]

Is Kc only for aqueous solutions while Kp is for gases because there was a question in the lecture where it had gases but was still using Kc?

[Anna Chen 1K]

Kc is defined by molar concentrations while Kp is defined by the partial pressures of the gasses.

[Sidharth D 1E]

Yes, they are both calculated the same way, and the states of the reactants and products will identify whether to use K_c or K_p.

[Ian Morris 3C]

Also, when answering, make sure each concentration is in brackets while pressure will be in parenthesis.

If given partial pressures we calculate Kp, but if concentrations are given we calculate Kc.

[Shrayes Raman]

Kc = Concentrions Kp = Partial Pressures. If given partial pressures use Kp and vice versa. This will tell you state of materials
