Answer 2

Answer:

The metals above hydrogen are more reactive than hydrogen. These metals can displace hydrogen from acids or water and liberate hydrogen gas. The metals copper, silver gold and platinum are less reactive than hydrogen and they do not replace hydrogen from water or acid. ... So zinc is more reactive than iron and copper.

Standard electrode potential of ECu2+/Cuo=0. 34V and EH+/Ho=0. 00V. This shows that copper is less reactive than hydrogen and Ecell0 of Cu is positive.
