Answer:
In case if the pellets of the calcium chloride gets crushed.
Step-by-step explanation:
When the pellets of calcium chloride get crushed it enhances the surface area of the compound. With the increase in surface area, the number of collisions in between the molecules of reactants increases. In the given case, the reactant molecules are water molecules and calcium chloride ions. In the procedure of dissolution, the calcium chloride ions get hydrated by the water molecules dipoles. As the frequency of the collision enhances, the activation energy gets lowered in order to begin the reaction.
