I want you to give me step by step solution and describe everything.

Fe²+ + O2(eq) + H+
eq
AG°f=(Fe2+ eq = -78.87),(02(eq)
If there is 0.001 M of Fe²+, 0.002M of Fe³+,8-
Will the forward rxn occur?
Step 1: balance the reaction.
Step 2 calculate AG° = -RT ln k
{C}c{D}a
{A}a {B}b
Step 3 calculate k
Step 4 calculate Q
=
=
{C} c{D}d
