Re: Ideal Gas Law
So the equation is PV=nRT. An example of using this problem is when we are given pressures and must find Kc. You would have to use the formula to convert to concentrations (n/V) of each individual molecule, then plug it into the Kc formula.

Re: Ideal Gas Law
Use it any time you think you need to obtain anything included in the equation (pressure, volume, moles, temperature), but aren't given values for one or more of the components of the equation.
Re: Ideal Gas Law
The ideal gas law is typically used to convert between pressure and concentration. So, if you're given concentration and you're supposed to find Kp or vice versa, you know that you have to apply the equation.

Re: Ideal Gas Law
I think the equation, PV=nRT, is more helpful in this class for understanding the proportionality between variables that influence the equilibrium constant k. For instance, as V decreases and thus P increases, their will be fewer mols of gas in your equation, which will affect k.

Re: Ideal Gas Law
Based on lectures/homework problems, the main use of the ideal gas law has been to convert between pressure and concentration of a gas.
