No solutions manual for my textbook and I can't figure out how to approach the problem. Any help would be extrememly appreciated!

a closed tank, water and gases have been brought into equilibrium x 10 2 eq liter 1: IFe2 J 2 x 10 M; pH 6.0; dissolved Fe(III) negligible but ferric hydroxide is precipitated. (a) What is the partial pressure of CO2? (b) What is the pe of the solution? (c) What partial pressure of O2 corresponds to this pe? The following information is available for the appropriate temperature: log K 1.5 CO2 H2O H2CO log K -6.3 log -10.3 log K +10.6 log K +38.0 Fes 30H Fe(OH) s) EO 1.23 V log K 14

Explanation / Answer

The partial pressure of carbon dioxide is approximately 0.00039 ATM which is equal to 0.0395 KPa or 0.296 mmHg or 0.005731 psi.
