Calculate the reaction quotient (Qc) for the chemical equation:2NO(g) + O2(g) ⇌ 2NO2(g)At a certain reaction conditions, the concentrations of NO, O2, and NO2 are 0.45 M, 0.25 M, and 0.60 M respectively. Determine if the reaction is at equilibrium and, if not, in which direction will it proceed to reach equilibrium.

A student is studying the electrochemical behavior of a certain metal ion in a solution of varying pH values. They have measured the anodic and cathodic Tafel slopes for the electrode reaction at each pH. The anodic Tafel slope values range from 60 mV/decade to 90 mV/decade, and the corresponding cathodic Tafel slope values range from 50 mV/decade to 70 mV/decade. Is this metal ion undergoing a one-electron or a two-electron transfer reaction? Justify your answer.
