Pick out the wrong statement.

Which of the following solutions will follow Raoult's law most closely ?

A minimum boiling azeotrope is exemplified by

The assumption made in Elis method in distillation is that enthalpy concentration lines of vapor and liquid are

Critical humidity of a solid salt means the humidity

Use of raschig rings in place of crushed stones as packing in packed beds (other things being same)

As complete saturation of an adsorbent is approached, the differential heat of adsrop-tion approaches

'Absorption with chemical reaction' is involved in the removal of

In paper industry, paper is dried in a __________ dryer.

The-relative volatility for separation of a non-ideal binary mixture by distillation should be

Pick out the wrong statement:

Pick out the wrong statement.

Only small amount of evaporation of water produces large cooling effects because of its

The most common packing used in industrial operations is __________ rings.

When the feed to a distillation column is a saturated liquid, slope of the feed line is

Leaching of sugar from sugar beets is done by

Absorption factor method is used to calculate the number of ideal stages, when

Flights in a rotary dryer are provided to

If f = moles of vapour present per mole of feed, then the slope of feed line is (Mcabe-Thiele method)

If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that

The rate of mass transfer is not dependent upon the
