Calculate Delta G_rxn at 298 K under the conditions shown below for the following reaction. 3O_2(g) rightarrow 2 O_3(g) Delta G degree = +326 kJ P(O_2) = 0.41 atm P(O_3) = 5.2 atm +341 kj +17.8 kj +332 kj -47.4 kj -109 kj What element is being oxidized in the following redox reaction? MnO_4^-(aq) + H_2C_2O_4(aq) rightarrow Mn^2+(aq) + CO_2(g) C O Mn H Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25 degree C. (The equation is balanced.) Sn(s) + 2 Ag^+ (aq) rightarrow Se^2+ (aq) + 2Ag(s) Sn^2(aq) + 2 e^- rightarrow Sn(s) E degree = -0.14 V Ag^+(aq) + e^- rightarrow Ag(s) E degree = +0.30 V +1.74 V +0.94 V +1.08 V -1.08 V -1.74 V Identify the characteristics of a spontaneous reaction Delta G degree 0 K > 1 all of the above none of the above
