The value of Ke for the reaction between water vapor and dichlorine monoxide is 0.0900 at 25°C. H₂O(g) + Cl₂0(g) → 2HOCI(g) 1st attempt Part 1 Determine the equilibrium concentration of H₂O if the starting concentrations of both reactants are 0.004124 M, with [HOCI], = 0.000 M. Part 2 M Determine the equilibrium concentration of Cl₂O. li! See Periodic Table M
