Just for clarification... the reaction is isothermal if delta U equals 0?

Yes, because temp doesnt change

Since internal energy (U) depends on temperature, in an isothermal process where temperature does not change internal energy will not change either. Therefore, delta U = 0 for an isothermal process.

Isothermal reactions have a constant temperature and since internal energy is a state function dependent on temperature, the internal energy change is zero.

Yes because if temperature is constant/not changing then the internal energy is therefore 0

Why does no temperature change = no change in U?
