Calculate the equilibrium constant (K) for an oxidation–reduction reaction (n = 2) with a standard cell potential (E°) of -0.51 V.

What is the standard cell potential (E°_cell) for the voltaic cell represented by the following cell diagram? Pt | H2(g, 1 atm) | 0.0025 M HCl || H+ (1 M) | H2(g, 1 atm) | Pt
