At 25C, H2O2 decomposes according to the following equation.2H2O2(aq) => 2H2O (l) + O2(g) .55Vi. Determine the value of the standard free energy change, Delta G, for the reaction at 25C.ii. Determine the value of equilibrium constant, Keq, for the reaction at 25C.iii. The standard reduction potential, E , for the half reaction O2(g) + 4H+(aq) + 4e- => 2H2O(l) has a value of 1.23V. Using this information in addition to the information given above, determine the value of the standard reduction potential, E, for the half reaction below.O2(g) + 2H+(aq) +2e- => H2O2(aq)
