Explanation / Answer

Lets number the reaction as 0, 1, 2, 3

required reaction can be written as:

required reaction = +1 * (reaction 1) -0.5 * (reaction 2) -0.5 * (reaction 3)

So, deltaHo rxn for required reaction will be:

deltaHo rxn = +1 * deltaHo rxn(reaction 1) -0.5 * deltaHo rxn(reaction 2) -0.5 * deltaHo rxn(reaction 3)

= +1 * (-393.5) -0.5 * (-566.0) -0.5 * (-483.6)

= 131.3 KJ

Answer: 131.3 KJ
