Lets number the reaction as 0, 1, 2 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 0 = -4 * (reaction 1) +1 * (reaction 2)
So, ΔHo rxn for required reaction will be:
ΔHo rxn = -4 * ΔHo rxn(reaction 1) +1 * ΔHo rxn(reaction 2)
= -4 * (157) +1 * (-1207)
= -1835 KJ
Answer: -1835 KJ
