Ideal gas law and [P]/[R]

Postby Jorja De Jesus 2C » Sat Jan 18, 2020 11:44 pm

When using PV=NRT, would finding the equilibrium constant only apply to pressure? Or could you use [P]/[R] with all the other variables?

I believe we are supposed to use the ideal gas equation only when we need to convert from Kp to Kc (from bars to moles).

You can also us pv=nRT when concerting from concentration to pressure; it goes both ways.

You use it to convert between pressure and concentration since concentration is (n/V).
