Question

Higher order (>3) reactions are rare due to

• A. Shifting of equilibrium towards reactants due to elastic collisions
• B. Loss of active species on collision
• C. Low probability of simultaneous collision of all reacting species
• D. Increase in entropy as more molecules are involved

Answer 1

The Correct Option is C

Higher-order reactions involving more than three reactant molecules are rare due to the extremely low probability of all reactant molecules colliding simultaneously with the correct orientation and sufficient energy to react. The probability of such collisions decreases as the number of reactants involved increases, making higher-order reactions less likely to occur.

So, the correct answer is (C) : Low probability of simultaneous collision of all reacting species.
