question

The standard E° for(1/2)F_2(g) + e^- \rightarrow F^-(aq), which is +2.87V, applies when the flouride ion concentration is 1M . What would the corresponding E be in 1M H_3O^+ , i.e., for the electrode reaction (1/2)F_2(g) + e^- + H_3O^+ \rightarrow HF(aq) +H_2O? (The K_diss of HF is 6.7 × 10^-4).
