Question
N2O(g) + CO(g) → N2(g) + CO2(g)
- The rate of the reaction represented above increases significantly in the presence of Pd(s). Which of the following best explains this observation?
A.
Pd increases the activation energy of the reaction.
B.
Pd absorbs the heat produced in the reaction.
C.✓ Correct
One of the reactants binds on the surface of Pd, which introduces an alternative reaction pathway with a lower activation energy.
D.
One of the products binds on the surface of Pd, which increases the reaction rate by decreasing the concentration of products in the mixture.
