I slept on it and when I woke up, I looked over it and figured out where I was going wrong. Had one of my concentrations wrong, so I kept getting the wrong value when I worked it. I already had the answer, I just couldn't figure out why my math wasn't producing it. Anyway, your method was...
I've been working on this one for a few days, and I just can't seem to get the right answer.
Consider the reaction I2(s) --> I- (aq) + IO3- (aq)
Balanced= 3I2 + 6OH- --> 5I- + IO3- + 3H2O
deltaG°= -153.8 kJ/mol
The question: What pH is required for the reaction to be at equilibrium...
