1. lactate is known to be a preferred substrate by some SRB, use thermodynamic principles to explore whether the following reaction could occur in an anaerobic digester environment:

CH3CHOHCOO^- + H₂O CH₃COO^- + CO₂ + 2H₂

If needed, you can assume lactate and acetate concentrations to be the same, and that the partial pressures of CO₂and CH₄ are 0.4 atm and 0.6 atm, respectively.
