Which reaction will most likely take place based on the activity series?

Li > K > Ba > Ca > Na > Mn > Zn > Cr > Fe > Cd > Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
Pt + FeCl3 Right arrow.
Mn + CaO Right arrow.
Li + ZnCO3 Right arrow.
Cu + 2KNO3 Right arrow.

Li + ZnCO3 will react.

Reason: Li is above Zn in the activity series, so lithium metal will displace zinc from its carbonate:
2 Li + ZnCO3 → Li2CO3 + Zn

The other combinations will not proceed because the single metal is less reactive than the metal in the compound (Pt < Fe, Mn < Ca, Cu < K).
