Assertion: Cu is less reactive than hydrogen. Reason : E_(Cu^(2+)//Cu)^(Theta) is negative.

Answer»

Both assertion and reason are true and the reason is the correct EXPLANATION of assertion.
Both assertion and reason are true and the reason is not the correct explanation of assertion.
Assertion is true but the reason is false.
Both assertion and reason are false.

Solution :Assertion is true, but the reason is false.
Standard electrode potential of `E^(@)" "CU^(2+)//Cu=0.34`
V and `E_(H^(+)//H_(2))^(Theta)=0.0V`. This shows that copper is less REACTIVE than HYDROGEN.
