Calculate the value of E' for each of the following reactions. Decide whether each is product-favored in the direction written. 
a) Bra(1) + Mg(s) + Mg₂+ (aq) +2 Br (aq) 
You may need to use the following data:
 Br₂(l) +2e⁻ +2 Br⁻ (aq) E° = +1.08 V 
Mg²⁺ (aq) + 2e⁻ + Mg(s) E° = -2.37 V 
E° = ____ V 
Reaction is ________
