Question
In a certain industrial process involving a heterogenous catalyst, the volume of the catalyst (in the shape of a sphere) is 10.0 cm^3. If the sphere were broken down into eight spheres each having a volume of 1.25 cm^3, 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 faster.
The second run will be slower.
The second run will have the same rate as the first.
The second run has twice the surface area.
The second run has eight times the surface area.
The second run has 10 times the surface area.
Explanation / Answer
effect of catalyst depands on surface area of catalyst, higher the surface area higher will be activity of catalyst and faster will be the raction.
here in first run : volume of sphere = 10 cm3
in second run sphere broken into 8 spheres so surface area of aphre increase that's why second run will be faster.
on dividing the sphere in 8 parts, surface area increase by two times so second run has twice the surface area.
so answers are:
the second run will be faster.
the second run has twice the surface area.
