What is Relative Volatility?

Relative volatility is a measure comparing the vapor pressures of the components in a liquid mixture of chemicals. It indicates the ease or difficulty of using distillation to separate the more volatile components from the less volatile components in a mixture.

What is Mass Transfer?

Mass transfer is a transport of components under a chemical potential gradient. The component moves to the direction of reducing concentration gradient. The transport occurs from a region of higher concentration to lower concentration.
