Answer

Brief Explanations:

A catalyst lowers the activation energy of a reaction. In the potential energy - reaction progress graph, the activation energy is the energy barrier that reactants must overcome to form products. The letter ( B ) represents the activation energy (the height of the energy barrier). Adding a catalyst reduces this activation energy. ( A ) represents the potential energy of reactants, ( C ) represents the potential energy difference between products and reactants (enthalpy change), and ( D ) is the peak of the energy barrier (related to activation energy but the catalyst reduces the height of this barrier which is represented by ( B )). So the quantity reduced by a catalyst is represented by ( B ).

Answer:

b) B
