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.
