Calculate the Equilibrium Constant for the Reaction Below at 25

question 64

Multiple Choice

Calculate the equilibrium constant for the reaction below at 25 °C. Co(s) + 2 Cr³⁺(aq) → Co²⁺(aq) + 2 Cr²⁺(aq)
The standard reduction potentials are as follows:
Co²⁺(aq) + 2 e^- → Co(s)
E° = -0.28 V
Cr³⁺(aq) + e^- → Cr²⁺(aq)
E° = -0.41 V
