Dear admins,

I would like seek your kind assistance to help me find out the value of constant a (bar L₂/mol2) and constant b (L/mol
) from Van Der Waals equation { [P + a(n/V)₂] (V/n - b) = RT } for the following materials.

1) Propadiene.
2) Methylacetylene

I usually find my answers from the list in this link below:
(You can’t post image, email or url links that are external to this domain. Please remove engineeringtoolbox com)

But both these materials are not listed.

Appreciate all the kind help.
Thank you.

Regards,
Kevin

Here we go

Propadiene a = 8,23 l^2* bar/ mol^2, b= 0,0747 l/mol
Methylacetylene is Propyne a = 8,4 l^2*bar/mol^2, b= 0,0744 l/mol
