A 1M solutions of Cu(NO3)2 is placed in a beaker with a strip of Cu metal while a 1M solution of SrSO4 is placed in the second beaker with a strip of Sr metal. The two beakers are connected by a salt bridge, and the two metal electrodes are linked by wires to a voltmeter at 25C. i) Write the half-cell reaction occurs at anode and cathode. ii) Calculate the standard cell potential under standard conditions. (4 marks) (2 marks) iii) Calculate the equilibrium constant if the cell voltage is 3.10V for non-standard conditions. (4 marks)
