Question

question 12 (1 point)
examine the figure below for the following question:

which letter presents the quantity that would be reduced if a catalyst were added to the reaction?

a) a

b) b

c) c

d) d

e) none of the above

Explanation:

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
