Kp from Kc

Postby Danielle_Cho_3A » Tue Jan 31, 2023 9:48 pm

I saw this formula come up in several of the syllabus problems (attached below). Is this something we should know for midterm 1, and if so, how do we know we are supposed to use it?

Yes I believe Lavelle went over how concentration and partial pressures are related when it comes to equilibrium calculations. That equation is just going from Kp to Kc, and in general I would say you do not need to memorize it as long as you understand the overall concept of how concentration = moles/vol, and how this can be substituted into the ideal gas equation.
