Answer to Question #184622 in General Chemistry for Aich80

Question

Using the standard reduction potentials, determine whether the following reactions are spontaneous under standard conditions:

A. Magnesium reducing chlorine to chloride ions

B. Silver reducing hydrogen ions to hydrogen

C. Cl₂ (g) + 2 i^-1 (aq) = 2Cl^-1 (aq) + i² (s)

Answer 1

c) The reaction is Spontaneous since chlorine has a more positive E°value, it will be more than capable of doing just that. This means that the first equilibrium reaction will actually move to the left, and the second equilibrium reaction will move to the right.
