Chemical Reaction Engineering -I Set 1

A first order gaseous phase reaction is catalysed by a non-porous solid. The kinetic rate constant and the external mass transfer co-efficients are k and kg respectively. The effective rate constant (keff) is given by

The half life period of a first order reaction is given by (where, K = rate constant. )

Catalyst is a substance, which __________ chemical reaction.

A chemical reaction is of zero order, when the reaction rate is (where, CA = concentration of reactant)

Higher free energy of activation of a chemical reaction (at a given temperature) implies

If the rate of a chemical reaction becomes slower at a given temperature, then the

The eddy diffusivity for a liquid in plug flow must be

The most suitable reactor for carrying out an auto-thermal reaction is a

In an ideal tubular-flow reactor

A reactor is generally termed as an autoclave, when it is a
