An example of a possible group discussion on this problem:

Linda: So what could be some possible reasons for the discrepancy between the measured conversion and the calculated conversion?

George: Well, there could be channeling in the reactor, which would make the catalyst less effective.

Susan: Also, maybe there isn't really 500 kg of catalyst in the reactor. Maybe there's less than what is specified.

Diane: Yes, or there might not be as much precious metal coating on the catalyst as we think. Maybe the catalyst isn't as good as expected.

Jeff: Do we know if the measured concentration is correct? That could cause the discrepancy also.

Linda: If the flow rate is too high, the conversion will go down as well. Maybe the flow needs to be controlled more effectively.

George: What about the pressure drop? It could be too large.

Susan: Let's calculate out one of these theories and see what kind of changes could affect the conversion.
