According to the collision theory, what two factors must be true for a given collision to successfully create products?
Rainbow [258]

Answer:

Sufficient concentration and correct orientation of particles

Explanation:

The collision theory postulates that, for a chemical reaction to occur, there must be collision between reacting particles.

It implies that the rate of reaction depends on the number of collisions per unit time as well as the fraction that are successful or effective.

For collisions to be effective, there must be proper orientation of the particles and right concentration of the reactants.

  • The number of effective collisions and rate of reaction are directly proportional to the concentration of of the reactants.
