Cell Potential and Spontaneity in Electrochemistry

In an electrochemical cell, the electrochemical potential is a crucial factor that governs the flow of electrons and overall cell reaction dynamics. Consider the galvanic cell represented by the half-reactions below, with standard reduction potentials (E°) as reported:

Ag⁺ + e^- → Ag (s); E° = +0.80 V

Cu²⁺ + 2e^- → Cu (s); E° = +0.34 V

Based on these half-reactions, determine the overall standard cell potential (E°_cell) for the galvanic cell, and identify the correct statement regarding the spontaneous nature of the reaction initiated by this electrochemical configuration.
