Question

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 1

Copper has a lower activity than hydrogen

Answer 2

Answer: Option (c) is the correct answer.

Step-by-step 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.
