Separation of two or more components of a liquid solution cannot be achieved by________?

If a nuclear reactor produces more fissile nuclear fuel than it consumes, then it is called a ________ reactor?

Experiments were conducted to determine the flux of a species A in a stagnant medium across a gas-liquid interface. The overall mass transfer co-efficient based on the liquid side for dilute systems for the above was estimated to be 4 × 10-3 kg mole/m2.s. The equilibrium data for the system is given as y = 2x. The flux across the interface (in kg mole/m2.s) for bulk concentrations of A in gas phase and liquid phase as y = 0.4 and x = 0.01 respectively is ________?
