Question

what is the main focus of collision theory in chemical reactions? a. the formation of new elements b. the likelihood of effective collisions c. the color change in reactions d. the phase change of substances

Explanation:

Collision theory in chemistry focuses on the idea that for a chemical reaction to occur, reactant particles must collide with sufficient energy and proper orientation. These are called effective collisions. Formation of new elements is related to nuclear reactions, color - change and phase - change are observable effects of reactions but not the focus of collision theory.

Answer:

B. The likelihood of effective collisions
