Answer 1

(1) an effective collision between reacting particles

Explanation:

In order for a chemical reaction to occur, an effective collision between reacting particles must always be.

• Based on the collision theory, for reactions to occur, there must be collisions between the reacting particles.
• It implies that the rate of reaction depends on the number of collision per unit time as well as the fraction of this collision that is successful or effective.
• For collisions to be effective, they must have adequate energy.
