Use standard reduction potentials to calculate the equilibrium constant for the reaction: Co2*(aq) + 2Cr2*(aq) Co(s) + 2Cr³*(aq) Hint: Carry at least 5 significant figures during intermediate calculations to avoid round off error when taking the antilogarithm. Equilibrium constant: AG° for this reaction would be than zero.

Use standard reduction potentials to calculate the equilibrium constant for the reaction: 2Ag+ (aq) + 21¯(aq) → 2Ag(s) + I₂ (s) Ag+ (aq) + e¯ → Ag(s) E = 0.799 V red I₂ (s) + 2e¯ → 21¯ (aq) Eº 0.535 V red - Hint: Carry at least 5 significant figures during intermediate calculations to avoid round off error when taking the antilogarithm. Equilibrium constant at 298 K: AGO for this reaction would be than zero.
