You constructed an electrochemical cell with lead at the cathode and zinc at the anode and measured a positive cell potential of 0.63 V. When placed in the same beaker, which combination of metal and ions will react spontaneously

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)
