This reaction is an example of an endothermic reaction. Let's solve the question. As the quantity of PVP increases, the size of ZnO nanoparticle reduces by two or three times. The direct in-core heating and instant on-off pulse of heat leads to the formation of a homogenous temperature gradient and reduces the reaction time. It is clear that SDS and CTAB are not suitable to produce ZnO nanoparticles because the products are aggregated to make large particles of several hundreds nanometer. Compound states [like (s) (aq) or (g)] are not required.
