Question

Langmuir Hinshelwood kinetics is followed by the reaction:

(a) Formation of hydrogen bromide

(b) Vapor phase decomposition of ethanal

(c) Cis-trans isomerization

(d) Reversible catalytic decomposition of isopropylbenzene

Answer 1

Right choice is (d) Reversible catalytic decomposition of isopropylbenzene

To elaborate: C6H5CH(CH3)2 ←→ C6H6 + C3H6

Let’s represent this reaction symbolically as  C ←→ B + P

the reaction follows the rate law  -r’C = [k(PC – PBPP/KP)] / [1 + KCPC + KBPB] which is the Langmuir Hinshelwood model.
