reactions is negative.
O
C. The sum of the voltages of the oxidation and reduction half-
reactions is positive.
O
D. The half-reaction for the reduced element has a negative standard
potential.


For apex the answer is b

Respuesta :

The answer is B for the apex answer

The redox reaction will be non-spontaneous when the sum of the voltages of the oxidation and reduction half reactions are negative.

What is a redox reaction?

A redox reaction is a chemical reaction in which there is a transfer of electrons from one species to another species. Both oxidation and reduction take place in this reaction and hence they are called redox.

Oxidation involves the loss of electrons or an increase in the oxidation state of the chemicals participating in the reaction. Reduction involves the gain of electrons or a decrease in the oxidation state of the participating chemicals.

For a redox reaction to be non-spontaneous, an external voltage has to be applied. The reaction has to have a negative potential. The sum of the voltages of the oxidation and reduction half reaction have to be negative.

Hence, B is the correct option.
