Question 9 a N20(9) + CO(9) - N2(9) + CO2(9) The rate of the reaction represented above increases significantly in the presence of Pd(s). Which of the following best explains this observation?
А Pd increases the activation energy of the reaction.
B Pd absorbs the heat produced in the reaction. C 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.​

Answer :

Answer:

Ans choise B

Explanation:

Increasing rates of reaction by catalysts always results because of decrease in activation energy occurs.
