Which of the following four statments are true for real gases and the corrections that must be made to the Ideal Gas Law?
a) particles do not repel or attract each other
b) the attraction of particles increases observed pressure
c) the volume of particles increases observed pressure
d) constant b corrects for attractions between particles
Which of the following four statments are true for real gases and the corrections that must be made to the Ide
you talk about van der Waals equation...
a) is wrong, because vdW equation was devised exactly because particles attract/repel
b) wrong, if particles are hold together more tightly, they are less likely to impact the container (= lower p)
c) CORRECT - the particles have less free volume as they themselves take up part of it, hence p increases
d) wrong; constant b corrects for volume of particles (ideal gas law assumes the particles have zero diameter!!)
