What are active centres?

1.	What are active centres?
Answer» 1. The surfiice of a catalyst is not smooth. It bears steps, cracks and corners. Hence the atoms on such locations of the surface are coordinatively unsaturated. 2. The have residual force of attraction. Such sites are called active centres. So the surface cames high surface free energy.
