Van der waals constants for neon and hydrogen r (a1 , b1 ) and (a2 , b2 ) respectively. What is the max no. of moles of Neon which will form a homogeneous mixture with n2 moles of hydrogen at 25degrees and constant pressure P ??

Since both Neon and Hydrogen are inert gases, so no stoichiometry reaction is possible.So it is difficult to predict the product.However , to solve any other vander waals question, you can use below formula.

{P+n^2 * a/v} {V-nb}

This is vanderwaals equation.
