Answer:

If there's an endothermic reaction that is spontaneous, then the reverse reaction is an exothermic reaction that's non-spontaneous. Melting ice is spontaneous at room temperature, but absorbs heat so it's endothermic. Therefore freezing of water at room temperature is an example, if you consider that a "reaction".
