Question
Higher order (>3) reactions are rare due to:
-
the increase in entropy and activation energy as more molecules are involved.
-
shifting of equilibrium towards reactants due to elastic collisions
-
loss of active species on a collision
-
low probability of simultaneous collision of all the reacting species
Solution
A.
the increase in entropy and activation energy as more molecules are involved.
Conditions for the occurrence of a reaction:
(i) Proper orientation and effective collision of the reactants.
(ii) the chances of simultaneous collision with proper orientation between more than 3 species are very rare, so reaction with order greater than 3 are rare.
