A non-standard state galvanic cell is constructed at 25.00°C as described here. The Fe(s) anode is immersed in a 0.040 M Fe(NO3)2 solution. The Cu(s) cathode is immersed in a 0.0060 M Cu(NO3)2. The circuit is completed with a salt bridge containing 1.0 M KNO3. The standard Fe/Fe2+ reduction potential is –0.44 V. The standard Cu/Cu2+ reduction potential is +0.34 V. Calculate the non-standard-state cell potential for this galvanic cell and determine if the reaction described is spontaneous under these conditions.
