Thread: Equation of state View Single Post
P: 125
 Quote by Studiot Since you know PV= RT where R is the gas constant, with P, V and T variables, you know that $$\frac{{PV}}{T} = R = {\rm{a}}\;{\rm{constant}}$$ We can rearrange this $$\left( {\frac{{PV}}{T} - R} \right) = {\rm{0}}$$ Isn't this now in the format you seek? However noting your other threads about Van der Waal's equation I wonder if your book was leading up to some more complicated function of P, V and T such as VDW.
Are you talking about the universal gas constant R? If so, you units are off.

R = universal gas constant = 8.3145 J/mol K

You need to specify the number of moles.
