Question

Which of the following reactions would be most spontaneous at 298K? A + 2B rightarrow C; E = + 0. 98V A + B rightarrow 2C; E =-0.030V A + B rightarrow 3C; E +0.15V A + B rightarrow C; E = + 1.22V More information is needed to determine, Given the following information: Cd(s)|Cd2+(aq)||Ag+(aq)|Ag(s) E = +1.20V Ag+(aq) + e- rightarrow Ag(s) E = +0.7999 Calculate E for: Cd2+(aq) + 2e- rightarrow Cd(s) +0.401V -0.401V +1.999V -1.999V +1.502V An electric current is passed through a 3.0M aqueous solution of H2SO4. What is the balanced half-reaction that occurs at the cathode? SO (aq) rightarrow SO3(g) + O2-(aq) SO3(g) + O2(aq) rightarrow SO (aq) Electric charge is conveniently measured in coloumbs (C). Mathematically, a coloumb is defined as IC = 1 Faraday Times 1 amp
