This is sufficiently near, and Tm = 372 K.

*xm by difference.

arm/r„ = (1.586/1.282) = 1.235 f = 1/(1 - 0.117) = (1/0.883) = 1.132

Hence Rm is not quite equal to 1.12.

8. Second approximation to reflux ratio A value of Rm = 1.08 will be tried.

Ln = (40 x 1.08) = 43.2 VB = (40 + 43.2) = 83.2 = Vm Lffi = 143.2 Taking = 355 K as before, then:
