Which of the following four statments are true for real gases and the corrections that must be made to the Ide

a) The constant a in van der Waals equation corrects for the attractions between gas particles.





b) The particles attract and repel each other.





c) The volume of the gas particles reduces the observed pressure.





d) The constant b in van der Waals equation corrects for the volume of real gas particles.

Which of the following four statments are true for real gases and the corrections that must be made to the Ide
a. true


b. true


c. false, it increases the pressure b/c it makes the volume smaller, if gas molecules really had no volume, then the observed pressure would be lower.





P=F/V, lower after subtracting volume of gas molecules --%26gt; higher P b/c denominator was lessened





d. true
