Will we need to know how to convert values of Kc to values of Kp, and vice versa? If so, how do we do this? Do you need to use the Ideal Gas Law (PV=nRT)? There were a few problems like this on a worksheet my TA gave me, so I just wanted to clarify.
I am not sure as to whether or not we will need to know how to do this, but basically you need to use the ideal gas law. If given pressure to get Kc, you need to put pressure into the ideal gas law and calculate the unknown values (most likely moles). Then use those moles to get concentrations and calculate Kc. There are more specific ways to describe this, but that is the basic way.
On one of the chemical equilibrium models, there are questions that Dr. Lavelle wrote that ask you to convert concentrations to pressures and vice versa. Yes, you would use the equation PV=nrt, and know that concentration is equal to P/rt. I would definitely study this because it was one the module post assessments
