Week 6 Clausius-Claperyon relation and Van der Waals equation Flashcards
1
Q
what is the Clausius Claperyon relation
A
dP/dT = S2-S1 / V2-V1 = ΔH / TΔV
2
Q
what can be said of ΔH
A
ΔH = Q if P is constant and dW = PdV
3
Q
what are the four ideal gas assumptions
A
> Particles are point like
All collisions are elastic
Particles dont interact with each other
Particles have mass but no charge
4
Q
what is the real gas equation
A
P = nRT/(V-nb) - an^2/V^2
5
Q
what does nb and an^2/V^2 represent in the real gas eqn
A
nb is the smallest volume the fluid can occupy
an^2/V^2 is the effect of weak attractions
6
Q
what is the real gas energy eqn
A
E(T,V) = E0(T) - an^2/V
7
Q
what is the entropy gibbs eqn
A
S = -(dG/dT)p
