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

The reaction proceeds too slowly to create products.

Copper has a higher activity than hydrogen and cannot replace it.

Copper has a lower activity than hydrogen and cannot replace it.

The reaction cannot occur because water is a reactant.

answer is Copper has a lower activity than hydrogen and cannot replace it.

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 [tex]H_{2}O[/tex] then there will be no reaction because copper is less reactive than hydrogen.

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