Fenske's equation for determining the minimum number of theoretical stages in distillation column holds good, when the

mixture (to be separated) shows negative deviation from ideality.

relative volatility is reasonably constant.

mixture (to be separated) shows positive deviation from ideality.

multicomponent distillation is involved.
