I have no idea what to write for the question...

"Is it reasonable to assume that the reaction velocity is directly proportional to absorbance? Why?"
"How could you determine if this is the case?"

Are those general questions or does an example exists? It is a bit difficult to give a precise answer.

General Questions
Okay, I give it a try.

I would reply the first question by refering to a graph: if proportionality between these units exists, the graph is increasing or decreasing in a linear way. This should be enough to reason your answer.

If the abosrbance has something to do with thermal energy (as in enzymes which are releasing it when set a reaction free), it can be determined by measuring the increasing temperature.

Thank you,

I wrote something along the lines of absorbance increasing with concentration and as concentration increases with absorbance we can determine that concentration is proportional to absorbance?

That sounds like proportional units. If the ceoncentration is depend on absorbance in that way, it is a linear relation of those ones. And that is a sign of proportionality.
