Q56 of 136 Page 42

Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : Cu is less reactive than hydrogen.


Reason : is negative


=+0.34V


= 0.00 V


Since, this radox couple have positive standard electrode potential, they are a weak reducing agent and therefore, Cu is less reactive than Hydrogen.


Hence, Cu is less reactive than Hydrogen as is positive.
