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.

Based on the activity series, the reactions that are most likely to take place are:

1. Pt + FeCl3 (This reaction will most likely occur since platinum (Pt) is higher in the activity series than iron (Fe))

2. Mn + CaO (This reaction will most likely occur since manganese (Mn) is higher in the activity series than calcium (Ca))

3. Li + ZnCO3 (This reaction will most likely occur since lithium (Li) is higher in the activity series than zinc (Zn))

4. Cu + 2KNO3 (This reaction will most likely occur since copper (Cu) is higher in the activity series than potassium (K))
