Question

(a) Most commercial heterogeneous catalysts are extremely
finely divided solid materials. Why is particle size
important?

Accepted Answer

Hi everyone for this problem. We're told the particle size of a heterogeneous catalyst is essential to its function. Which of the following is the most efficient heterogeneous catalyst. So, something important here is that we're told the particle size is essential to its function and we want to know which of the following answer choices is going to be the most efficient. So because we're looking at particle size, let's look at it in terms of what's going to increase the rate of our reaction. So if we have a small particle size, what that means is we're going to have a larger surface area. Okay. And by having a larger surface area. This is important when it comes to active sites, by having a larger surface area, we have more active sites, which is going to increase the reaction rate. So for all of the answers, choices given our smart smallest particle size is going to be the most efficient and fine powder is going to be our smallest particle size. So this is going to make answer choice B our most efficient heterogeneous catalyst. Okay. Due to that particle size, that's the end of this problem. And that's the answer to this problem. I hope this was helpful
