B.) Diluting the vinegar because more you dilute, more will be dissociation constant and hence more H+ ions of vinegar will react with OH- ions of NaOH.
Hope this helps!

Answer: Option (B) is the correct answer.

Explanation:

When we dilute the vinegar then there will be a decrease in vinegar particles. That is, there will be decrease in number of solute particles in the solvent.

Hence, there will be less number of collisions between the vinegar and sodium hydroxide. Therefore, there will be a decrease in rate of reaction.

Thus, we can conclude that out of the given options diluting the vinegar  would decrease the rate of a reaction between vinegar and sodium hydroxide, is the correct option.
