Suppose a reaction started out with T=290k. Then, it was heated to T=295K. Then, it was cooled back down to T=290K.
Would we still say this reaction overall is isothermal and thus delta U=0?

The delta T of the system would be zero if you are calculating the entire process: 290 to 295 to 290. Delta T = 290-290. If no work is done by the system during the heating and cooling, then Delta U = 0.

Remember. Tfinal-Tinital, even though there are changes, ultimately you will go back down to the same temperature, so your response would become 0.
