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 = +1 * (reaction 1) +1 * (reaction 2)
So, ΔGo rxn for required reaction will be:
ΔGo rxn = +1 * ΔGo rxn(reaction 1) +1 * ΔGo rxn(reaction 2)
= +1 * (-152.0) +1 * (210.0)
= 58 KJ
Answer: 58 KJ
