Question: Higher order (>3) reactions are rare due to :-
shifting of equilibrium towards reactants due to elastic collision
loss of active species on collision
low probability of simultaneous collision of all the reacting species
increase in entropy and activation energy as more molecules are involved.
Correct Option: , 3
Solution:
Higher order (>3) reaction are rare due to low probability of simulatneous collision of more than three molecuels.
