Expert Answer
Oxidation reactions are both endo-and exothermic depending upon the reaction conditions.
Consider the following equations.
As you can see from these reactions that Heat is released in the reaction so it is an exothermic reaction.
I2(s) + Cl2(g) -----------> 2 ICl (g)
delta H = + 17.8 kJ/mol
delta G = -5.5 kJ/mol
This oxidation reaction is spontaneous, but endothermic.
