Question

Select the incorrect statement about the adsorption theory from the following option.

(a) The surface of the solid catalyst possess some isolated active centres having residual affinity

(b) Due to these centres, the molecules of the gaseous reactants get adsorbed in unimolecular thick layer

(c) The adsorbed reactants get activated and then react

(d) The energy required for activation is more than that required for uncatalysed reaction

The question was posed to me during a job interview.

Query is from Catalysis in portion Reaction Dynamics of Engineering Chemistry I

Answer 1

The correct option is (d) The energy required for activation is more than that required for uncatalysed reaction

Easiest explanation: The energy required for activation is less than that required for uncatalysed reaction, and hence the reaction goes faster. All the other options are correct.
