Historically, chromium (Cr) has been used in numerous industrial processes, including leather tanning and metal plating operations. In these applications, if the water is mildly acidic, the Cr is typically present as bichromate (HCrO4) and/or dichromate (Cr2O72-) ions. These ions can be interconverted by the reaction: Cr₂O7²- + H₂O The standard Gibbs energies of formation of HCrO4, Cr2O72, and H₂O are -764.8, -1301, and -237.18 kJ/mol, respectively. Compute the equilibrium constant for the conversion of HCrO4 to Cr₂O7²-. 2HCrO4
