Isothermic Reactions and Heat

[Sylvia Zhang 2L]

If a reaction is isothermic, can it still involve a change in heat?

[Jasmine Winter 1A]

Isothermic means that a reaction has equal or constant heat for both the products and the reactants; I would guess there is no heat exchange going on. If there is a heat exchange, the heat lost is equal to the heat gained and vice versa.

It likely does not involve a change in heat simply because the overall change in temperature is or would be 0.

[Leewon Koo 2K]

I think it cannot have a change in temperature as T stays constant. The heat going into an isothermal reversible expansion reaction is negated by the increase in volume so overall temperature never changes.
