Molecules must collide at a low enough energy to break bonds.

Molecules must divide at a low enough energy to break bonds.
Molecules must divide at a low enough energy to break bonds.

Molecules must collide at a high enough energy to break bonds.
Molecules must collide at a high enough energy to break bonds.

Molecules must divide at a high enough energy to break bonds.

Answer 1

Molecules must collide at a high enough energy to break bonds.

(According to collision theory, reactant molecules must collide with sufficient energy (≥ activation energy) and proper orientation for a reaction to occur.)
