according to the left side graph,
Q1. status 1 is when P(pressure)=1atm
then calculate the value of z, and V
z is the compressibility factor
Q2. status 2 is when factor z has the minimum value,
dz/dP=dz/dV=0
then calculate the value of z, P, V
Q3. status 3 is when factor z =1
then calculate the value of P,V
i dont know how to derive the value of z, P,V in each question
please notice me the process to derive the yellow part.
+ answers of each questions are
status 1
ans
z=1-a/(RT)^2 , P=1atm, V = RTz or RT
status 2
………
see the picture of yellow parts
