Answer:
d
Explanation:
It increases the reaction rate by lowering the activation energy for a reaction
Catalysts increase the rate of a reaction by lowering the activation energy of a reaction. Thus, Option D is correct.
Energy is defined as the capacity to do work, while activation energy is completely different that is In a chemical reaction the energy required to form an activated complex .
In a chemical reaction minimum amount of extra energy required by a reactant to convert into product called activation energy.
It can be represented as Ea and measured in the form of joules or kilojoules per mole or kilocalories per mole.
Two major factors which influence activation energy, such as Nature of Reactants like ionic reactant.
Here the value activation energy will be due to an attraction between two reactants.
Second factor is the role of Catalyst, that is positive catalyst will lower the activation energy where as negative catalyst increase the activation energy.
Hence, Option D is correct.
