Question

Higher order $(>3)$ reactions are rare due to

• A. low probability of simultaneous collision of all the reacting species
• B. increase in entropy and activation energy as more molecules are involved
• C. shifting of equilibrium towards reactants due to elastic collisions
• D. loss of active species on collision

Answer 1

Answer: (A)

molecularity and order $>3$ is not possible because of low probability of simultaneous collision of all the reacting species.
