1. For each of the following redox reactions: i. Write the oxidation half reaction ii. Write the reduction half reaction ii. Determine the Ecell at 25°C iv. Using the Eceu determine the Free Gibbs Energy in kJ/mol V. Based on the Ecelu and Free Gibbs Energy determine whether the reaction is spontaneous or nonspontaneous. a. 2F23*(aq) + I'(aq) → 2FE2*(aq) + I2(s) b. Cr20,2(aq) + 6Fe2*(aq) + 14H*(aq) → 2Cr³*(aq) + 6FE3*(aq) + 7H2O(1)
