The chemical reaction involved in the oxidation of hydroquinone by hydrogen peroxide to produce quinone and water is: C6H4 (OH)2 (aq) + H2O2 (aq) = C6H4O2 (aq) + 2 H20 (l). Calculate delta H for the above reaction from the following data. C6H4 (OH)2 (aq) = C6H4O2 (aq) + H2 (g) delta H = 177.4 kJ; H2(g) + O2 (g) = H2O2 (aq) delta H = -191.2 kJ; H2 (g) = 1/2 O2 (g) = H2O (g) delta H = -241.8 kJ; H2O (g) = H2O (l) delta H = -43.8 kJ. The enthapy for the oxidation of hydroquinone by hydrogen peroxide to produce water and quinone is _________kJ
