Which of the following features is important for a solid catalyst to have a high surface area?
High density
Small particle size
Low porosity
High crystallinity
A high surface area is important for a solid catalyst as it provides more active sites for reactants to bind to. One factor that can contribute to a high surface area is a small particle size, as smaller particles have a larger surface area-to-volume ratio. High density, low porosity, and high crystallinity may not necessarily be important for achieving a high surface area.
