According to the collision theory for chemical reactions why do most reactions rates increase g

When a catalyst is involved in the collisionbetween the reactant molecules, less energy is required for the chemicalchange to take place, and hence more collisions have sufficient energy for reaction to occur. The reaction rate therefore increases. Collision theory is closely related to chemical kinetics

Hydrogen is the most abundant element on the periodic table..hope it .

It shows that the experiment is designed properly.
