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

The correct option is A low probability of simultaneous collision of all the reacting species

The main conditions for the occurrence of a reaction are proper orientation and effective collision of the reactants.

Since the chances of simultaneous collision with proper orientation between two species in high order reactions are very rare, so reaction with order greater than 3 is rare.
