Textbook Question

Chapter 1, Problem 1.25P

Platinum is an expensive and rare metal used incatalytic converters. Much research has been devoted to maximizing reactive properties of other less expensive metals by reducing their size to the nanoscale. Smaller particles are more reactive because they have a larger surface area to volume ratio. Whichtype of an atom in a nanoparticle is more reactive?
(a) An atom on the surface of a particle
(b) An atom in the interior of a particle
(c) The location of an atom in the nanoparticle does not influence its reactivity.
