Question

Why does the reaction H2O + Cu→no reaction not proceed to a product?

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

It is known that a stronger element is able to displace a less stronger element in a chemical reaction.

And, according to the reactivity chart hydrogen is more reactive in nature than copper.

Therefore, when Cu is added to $H_{2}O$ then there will be no reaction because copper is less reactive than hydrogen.

Thus, we can conclude that the reaction $H_{2}O+Cu \rightarrow \text{no reaction}$ not proceed to a product because copper has a lower activity than hydrogen and cannot replace it.

Answer 2

Copper has a lower activity than hydrogen
