In Vander Waals equation \(\left[ P +\frac{ a }{ V ^{2}}\right][ V - b ]= RT\); \(P\) is pressure, \(V\) is volume, \(R\) is universal gas constant and \(T\) is temperature. The ratio of constants \(\frac{a}{b}\) is dimensionally equal to .................
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) \(PV\)
Step-by-step Solution
Detailed explanation
By principle of homogenity
\({[ P ]=\left[\frac{ a }{ v ^{2}}\right] \text { and }[ b ]=[ v ]}\)
\(\Rightarrow\left[\frac{ a }{ b }\right]=[ PV ]\)
