Product description

4.21. The reaction of CO NO in the presence of palladium Pd20–30 nanoclusters proceeds at 300 K, which is 150 K lower than the reaction temperature catalyzed by metal single crystals. Using the Arrhenius equation for the rate constant, estimate how many times the clusters reduce the activation energy compared to single crystals (assume that the value of A does not depend on the particle size Pd).
