In a certain industrial process involving a heterogenous catalyst, the volume of the catalyst (in the shape of a sphere) is 10.0cm cubed. If teh sphere were broken down into eight spheres each having a volume of 1.25cm cubed, and the reaction is run a second time, which of the following accurately characterizes the second run? Choose all that apply.
The second run will be fasterThe second run will be slowerThe second run will have the same rate as the firstThe second run has twice the surface areaThe second run has eight times the surface areaThe second run has 10 times the surface area
