Answer:
D
Explanation:
Catalysts lower the activation energy of the reactants so the reaction proceeds faster than naturally. The catalyst does not change the reaction (the potential energy of the reaction remains the same) in any other way and is not caused by the reaction.
Answer: Option (D) is the correct answer.
Explanation:
A catalyst is defined as the substance which lowers the activation energy of a chemical reaction without itself getting consumed in the reaction so that there will be increase in rate of reaction.
As catalyst, basically lowers the activation energy so that reactant molecules with lower energy can also participate in the reaction. Hence, more number of collisions can occur due to which there is rapid formation of products.
Thus, we can conclude that the statement catalysts reduce the energy needed for the reaction to take place, is true about catalysts.
