A) \[\left( P+\frac{a}{T{{(V+C)}^{2}}} \right)(V-b)=RT\]
B) \[\left( P+\frac{a}{T{{(V-C)}^{2}}} \right)(V-b)=RT\]
C) \[\left( P+\frac{a}{T{{V}^{2}}} \right)(V-b)=RT\]
D) \[\left( P+\frac{a}{T{{V}^{2}}} \right)(V+b)=RT\]
Correct Answer: C
Solution :
Berthelot equation is: \[P+\frac{a}{T{{V}^{2}}}(V-b)=RT\] He introduce the volume correction in van der Waals equation, but the pressure correction was different. He introduced the correction as \[\frac{a}{T{{V}^{2}}}\] in place of \[\frac{a}{{{V}^{2}}}\].
