Homework Answers
Lets number the reaction as 1, 2, 3 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 3 = -1 * (reaction 1) -2 * (reaction 2)
So, ΔHo rxn for required reaction will be:
ΔHo rxn = -1 * ΔHo rxn(reaction 1) -2 * ΔHo rxn(reaction 2)
= -1 * (-127.6) -2 * (29.4)
= 68.8 KJ
Answer: 68.8 KJ
