A galvanic cell is constructed using the standard half cells Al3(aq)/Al(s) and Cl2(g)/cl (aq). ( E red(AL3+/Al) = -1.66 V= and E red(CI2/CI-) = 1.358 V) A). Write equation for the reactions at the anode and cathode. B). Write balanced equation for the overall reaction C). What is the abbreviated cell notation ? D). Make a sketch of the call and label cathode and anode, the charges on each electrode, the direction of ion flow and the direction of the electron flow. E). Calculate the standard cell potential F). What is the value of the equilibrium constant at 25 C
Given the information given below, what is the standard enthalpy change for the reaction: W(s) + 3H2O(g) => WO3(s) + 3H2(g)? 2W(s) + 3O2(g) => 2WO3(s) ?Ho = -1685.4 kJ 2H2(g) + O2(g) => 2H2O(g) ?Ho = -477.84 kJ
