When do you know that a gold ring will dissolve based off of delta G standard?

When Dr. Lavelle showed us an example like this during lecture, we had not yet learned the Nernst equation, so you could use to see if the reaction is spontaneous or not. If the
is positive, the reaction would be unfavorable, and the ring would not dissolve. However, if the is negative, then we know that the reaction is favorable and spontaneous, and the ring will dissolve.

Can we assume that any spontaneous reaction will dissolve? Does this apply to only this reaction?
