Question

What are effective collisions?

• A. Collisions leading to the transformation of reactants to products
• B. formation of activated complex
• C. collison between two reactant to decrease the activation energy
• D. collison between two reactant to overcome activation energy barrier

Answer 1

Answer: (B), (D)

The correct options are
B formation of activated complex
D collison between two reactant to overcome activation energy barrier

The effective collisions are collisions leading to the transformation of reactants to products.
This will happen when (i) the reactant species collide (ii) the colliding molecules have total kinetic energy equal to or greater than the activation energy of the reaction (iii) the colliding molecules must have proper orientation relative to each other.
