Question

Q. critical temperature and critical pressure of clorine 419k and 93.1 atm sphere res. calculate the value der - waal's constant for clorine gas
Given -
tc =419k
PC = 93.1 atom​

Answer 1

Answer:

Explanation:

Use Tc=8a/27Rb and Pc=a/27b^2

Then a=419*27*0.0821/8 from Tc

a=93.1*27*b^2 from Pc

Since LHS are equal, Equate RHS

you get b

Put value of b in Pc or Tc to get a
