Question

[Gradpoint-Question AK-3] Acid is added to a beaker containing crushed marble. What effect does stirring this mixture have on the system?

A: The number of particle collisions increases

B: The surface area of the particles increases

C: The energy of the collisions increases

Answer 1

A : The number of particle collision increases

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step explanation:

According to collision theory, more is the number of collisions between molecules of reactants more will be the rate of reaction.

Therefore, when we increase stirring in a beaker then it will create disturbance between the reactant molecules due to which there will be increase in number of collisions.

Hence, we can conclude that effect of stirring the given mixture on the system will be that the number of particle collisions increases.
