Lets number the reaction as 1, 2, 3, 4 from top to bottom
required reaction should be written in terms of other reaction
This is Hess Law
required reaction can be written as:
reaction 4 = -1 * (reaction 1) +1 * (reaction 2) +1 * (reaction 3)
So, ΔHo rxn for required reaction will be:
ΔHo rxn = -1 * ΔHo rxn(reaction 1) +1 * ΔHo rxn(reaction 2) +1 * ΔHo rxn(reaction 3)
= -1 * (-890.4) +1 * (-393.5) +1 * (-221.0)
= 275.9 KJ
Answer: 275.9 KJ
