Question

TuteeHUB · Accepted Answer

Catalyst increases the number of collisions between the reacting molecules.

TuteeHUB · Answer

Catalyst decreases the rate of backward reaction so that rate of forward reaction increases

TuteeHUB · Answer

Catalyst provides extra energy to reacting molecules so that they produce effective collisions

TuteeHUB · Answer

Catalyst provides an alternative path of lower activation energy to the reactants
