All right, sure, i'll help you out here.
00:01
So let's start by saying this.
00:03
If you see kc, that that is typically written as your normal equilibrium constant.
00:09
And as you know, you can see you've got this formula that you can use to turn kp's into kc's, where you take the gas constant times the temperature raised to the delta n, and the delta n is equal to the moles of gaseous products minus the moles of gaseous reactants.
00:30
Okay, and your temperature is typically 298 kelvin.
00:35
Make sure it's a kelvin, and this one is your gas constant.
00:40
Okay, so with your different scenarios here, if you're given concentrations, that one you're going to use kc or just keq, because i use those interchangeably.
00:53
Concentrations are a normal one.
00:55
If you're given pressures, then you're going to use the kp, because that's the one that's related to pressures.
01:01
If you're given grams, what you're going to need to do is turn your grams into moles using stoichiometry.
01:11
And then you can divide all of those by whatever the volume is, and that will turn them into concentrations.
01:18
And then you can use your kc like we were doing before.
