Question

What must happen before a chemical reaction can begin

Answer 1

This is because in any chemical reaction, chemical bonds in the reactants are broken, and new bonds in the products are formed. Therefore, in order to effectively initiate a reaction, the reactants must be moving fast enough (with enough kinetic energy) so that they collide with sufficient force for bonds to break.

Answer 2

The activation energy must be reached. The energy required to break the bonds of reactant molecules. Catalyst work by decreasing the activation energy of a reaction. If the activation energy required for a chemical reaction were reduced, If the activation energy required for a chemical reaction were reduced.
