(c) The cell represented below was set up under standard conditions.
Pt|Fe2+(aq), Fe3+(aq)||Tl3+(aq),Tl+(aq)|Pt Cell e.m.f. = + 0.48 V
(i) Deduce the standard electrode potential for the following half-reaction.
Tl3+(aq) + 2e– → Tl+(aq)

(ii) Write an equation for the spontaneous cell reaction.

Hi everyone i did the Q did it well - apart from spontaneous reaction i got 2fe3+ + Tl3+ ====) 2Fe2+ + Tl+
This was by using the anti-clockwise rule = however - the real answer for the Q was
Tl3+ + 2 Fe2+ ===) 2Fe3+ + T1+
Need an explanation why thanks!
