Explanation / Answer

Ans 6

The elements that lie above in the activity series tend to oxidise faster than the ones lying below them.

So here :

a) Spontaneous

Since Fe lies above Cu in the activity series.

b) b)Non spontaneous

Since Na lies above Sn in activity series

c) b) Non spontaneous

Since Mn lies above Pb in activity series.

d) A) spontaneous

Since Al lies above H2 in activity series.
