Answer:

It is greater than -600kJ/mol and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.

Explanation:

In an endothermic reaction, the reaction requires a determined amount of energy to occurs.

The reaction of the problem has H = -600kJ/mol. The reaction is endothermic and the energy that the reaction needs is absorbed by the reactants. That means, the energy of products:

Is greater than -600kJ/mol and the amount of energy required to break bonds is greater than the amount of energy released in forming bonds.

Explain why diamonds are useful for electrodes in batteries
umka21 [38]

Answer:

Diamonds have a broader potential window of 3 to 5 volts.

Explanation:

The minimum voltage required for electrolysis is called potential window. Electrodes such as titanium electrodes and those made of noble metals have a potential window of about 2 volts. Diamond has a potential window of 3 to 5 volts that makes it preferentially start a redox reaction of a substance that is difficult to electrolyze. This facilitates electrolysis of substance that were difficult to decompose in normal electrochemical systems.
