Which of the following is a desirable feature of a solid catalyst in terms of its active sites?
A low density of active sites
A high energy barrier for reactants to overcome
A range of different types of active sites
Active sites that are easily deactivated by reactants
Answers (1)
A range of different types of active sites on a solid catalyst can increase its ability to catalyze a variety of reactions. Different types of active sites can bind to different reactants, leading to a wider range of possible reaction pathways. A low density of active sites or high energy barriers may limit the efficiency of the catalyst, while active sites that are easily deactivated can limit its stability and lifespan A desirable feature of a solid catalyst in terms of its active sites is that it has a high density of accessible active sites. Active sites are the regions on the surface of the catalyst where reactant molecules can adsorb and undergo chemical reactions. A high density of active sites means that more reactant molecules can be adsorbed and react simultaneously, leading to a higher reaction rate and higher conversion efficiency.
