Question

Which of the following does not affect the rate of reaction?
(1) Amount of the reactant taken
(2) Physical state of the reactant
(3) del H of reaction
(4) Size of vessel

Answer 1

4) size of the vessel .

Answer 2

Size of vessel does not affect the rate of reaction.

Option (4).

Explanation:

• The rate of the reaction is been affected by the amount of the reactant taken, the more the amount the more time for the reaction.

• And also the physical state of the reactant matters in a chemical reaction.

• But the size of the vessel does not matter and surely does not affect the rate of the reaction.

• Here the rate of the reaction does not depend on the size of the vessels.

• Because it fully depends on the temperature, reactant, size of particles, etc.
