Zinc will react with lead nitrate but not calcium chloride because zinc is higher than lead on the reactivity series.
Reactivity series
The reactivity series of metals can be seen in the attached image.
From the image, Zn is seen as being less reactive than Ca but more reactive than Pb. The higher the location of a metal on the series, the more its reactivity.
Thus, Zn cannot displace Ca in CaCl2 and thus will not react. However, Zn can displace Pb from PbNO3 and thus will react.
