Question

Which is a characteristic of a catalyst?

• A. It Initiates the reaction.
• B. It alters the rate of reaction.
• C. It Increases the average kinetic energy of the molecule
• D. Both B and C.

Answer 1

The correct option is D

Both B and C.

The explanation for the correct options:

Option D: Both B and C.

• Catalysts are employed to quicken or boost the pace of the reaction.
• By providing a different route with lower activation energy, a catalyst speeds up the process.
• In general, catalysts react with reactants to produce intermediates while also speeding up the creation of the ultimate reaction product.
• Even while the catalyst won't be consumed or depleted throughout the reaction, it nevertheless participates in the process.

Option B: It alters the rate of reaction.

• Catalyst can lead to an alteration in the rate of the reaction.
• To speed up the reaction, a very little quantity of catalyst is required.

Option C: It Increases the average kinetic energy of the molecule

• It raises the molecule's typical kinetic energy.

The explanation for the incorrect option:

Option A: It Initiates the reaction.

• A chemical reaction can never be started by a catalyst.
• The reaction is already taking place, however slowly, and the catalyst just accelerates it.

Therefore, the correct option is Option (D) : Both B and C.
