Chlorine dioxide (C1O₂), which is produced by the reaction

$2{\text{NaC1O}}_{\text{2}}\left(aq\right)+{\text{ Cl}}_{\text{2}}(g)\to {\text{2ClO}}_{\text{2}}(g)+\text{ 2NaCl}\left(aq\right)$

has been tested as a disinfectant for municipal water treatment. Using data from Table 17-1, calculate  and ∆G° at 25°C for the production of ClO₂.
