Calculate the rate of the electrochemical reaction that takes place in the following electrolytic cell:Cu(s) | Cu2+(aq, 0.050 M) || Ag+(aq, 0.010 M) | Ag(s)Given that the current density is 0.500 A/m2 and the Faraday constant is 96,485 C/mol. The reduction potential of Cu2+(aq) + 2e- → Cu(s) is +0.34 V, and the reduction potential of Ag+(aq) + e- → Ag(s) is +0.80 V. Assume the temperature is 25°C and one-unit charge is exchanged.

Assuming you have the equilibrium constant value for a given chemical equation, determine the concentration of products and reactants at equilibrium for the reaction: N2(g) + 3H2(g) ⇌ 2NH3(g); Kc = 6.0 x 10^2 at 500°C. If the initial concentration of N2 is 0.1 M and the initial concentration of H2 is 0.2 M, what is the concentration of NH3 at equilibrium?
