Pore volume

Surface area

Solid density

All of these

The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor

The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour

None of these

The unit of space velocity is (time)⁻¹

Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect on the rate of adsorption per site

Whole surface of the catalyst does not have the same activity for adsorption and there is attraction between the adsorbed molecule

All the adsorption does not take place by the same mechanism

Extent of adsorption is more than one complete monomolecular layer on the surface
