WebAug 8, 2024 · Explanation: Zinc in copper sulfate solution is an example of displacement reaction. As is evident from the reactivity series, zinc is more reactive than copper. Zinc gets oxidized, Z n → Z n 2 + + 2 e − , in the process, it releases 2 electrons. What will happen when copper and zinc is mixed? Webcopper holds on to its valence electrons more tightly than zinc 2. If the formation of Cu 2+ (g) from Cu (g) absorbs 2703 kJ/mol, and the formation of Zn (g) from Zn 2+ (g) releases 2640 kJ/mol, give the reaction enthalpy for Zn (g) + Cu 2+ (g) = Cu (g) + Zn 2+ (g) none of these -5343 kJ -63 kJ +5343 kJ +63 kJ 3.
