Select correct statements :

A

Langmuir adsorption isotherm is expected to be applicable at low gas pressure and moderately high temperature.

B

The rate of an enzyme catalysed reaction depends upon enzyme concentration.

C

A negative catalyst raises the activation energy barrier of a reaction and thus reduces its rate.

D

In physisorption gases having higher critical temperature are adsorbed to a greater extent than those with lower critical temperature.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
A negative catalyst does not raises the activation energy barrier of a reaction, it actually functions to remove the active intermediate from the reaction and thus, it retards the rate of a reaction.
