Question: The activity series in Section 4.4 shows that reaction (a) is spontaneous while reaction (b) is non spontaneous at 25C: (a) Fe(s) + 2H+ Fe2+(aq)

The activity series in Section 4.4 shows that reaction
(a) is spontaneous while reaction (b) is non spontaneous at 25°C:
(a) Fe(s) + 2H+→ Fe2+(aq) + H2(g)
(b) Cu(s) + 2H+→ Cu2+(aq) + H2(g)
Use the data in Appendix 3 to calculate the equilibrium constant for these reactions and hence confirm that the activity series is correct.
