Scoring Scheme: 3-3-2-1 When you use the half reaction method to balance the redox reaction between one mole of NBS and ascorbic
acid to give L-dehydroascorbic acid and succinimide, how many moles of electrons are transferred?
1 answer:
<span>In the redox reaction between one mole of NBS and ascorbic acid, ascorbic acid undergoes oxidation reaction to form </span><span>L-dehydroascorbic acid.
On other hand, N-bromo</span>succinimide (NBS) undergoes reduction to form <span>succinimide.
Electron transferred during this process is two. Complete reaction is attached below for quick reference.
Thus, one molecule of NBS reacts with one molecule of </span>ascorbic acid, during this redox reaction. For each molecule reacting, two electrons are transferred.
Thus, when one mole of NBS reacts with one mole of ascorbic acid, 2 x Na moles of electrons will be transferred. It may be noted here that, Na = Avagadro's number = 6.022 X 10^23.
On other hand, N-bromo</span>succinimide (NBS) undergoes reduction to form <span>succinimide.
Electron transferred during this process is two. Complete reaction is attached below for quick reference.
Thus, one molecule of NBS reacts with one molecule of </span>ascorbic acid, during this redox reaction. For each molecule reacting, two electrons are transferred.
Thus, when one mole of NBS reacts with one mole of ascorbic acid, 2 x Na moles of electrons will be transferred. It may be noted here that, Na = Avagadro's number = 6.022 X 10^23.

For the given reaction, according to the Law of Conservation of Energy, the energy required to decompose Hcl and produce are equal.
Answer: Option C
<u>Explanation:</u>
According to law of conservation's of energy, energy can only be transferred from reactants to product side. So in this process, it is stated that 185 kJ of energy will be needed to decompose it. So that 185 kJ of energy will be getting transferred to produce the creation of hydrogen and chloride in the product side.
So if we see from the reactants side, the energy of 185 kJ is required for decomposition of hydrogen chloride. Similarly, if we see from the product side, the 185 kJ utilized for decomposition is transferred as energy required to create hydrogen and chlorine atoms. This statement will be in accordance with the law of conservation's of energy.
