a. Consider a galvanic cell based on the reaction Al)+Mg() Al (+Mg) i. Give the cell reaction ii. b. i. Calculate 4G for the reaction Calculate E cell for the cell. 2 mks 2 mks ii. Is this reaction spontaneous? If so explain your answer. 2 mks c. i. Combine the equation: AG = AH-TAS AG = -FE to derive an expression for E cell as a function of temperature. 4 mks ii. Describe how one can graphically determine AH and AS from measurements of E cell at different temperatures. 4 mks
