###### FREE Expert Solution

(1) N2(g) +  O2(g) →  2NO(g)           ΔH = + 180.7

(2) 2NO(g) + O2(g) → 2NO2(g)        ΔH = -113.1

(3) 2N2O(g) →  2N2(g) + O2(g)        ΔH = -163.2

We shall modify the given reactions to arrive at the overall reaction. Any modification to the reaction is reflected in the value of ΔH for the reaction.

You may want to reference(Pages 183 - 186)Section 5.6 while completing this problem.

Given the following data:

N2(g) +  O2(g) →  2NO(g)           ΔH = + 180.7
2NO(g) + O2(g) → 2NO2(g)        ΔH = -113.1
2N2O(g) →  2N2(g) + O2(g)        ΔH = -163.2

Use Hess's Law to calculate H for the following reaction:

N2O(g) + NO2(g)  →  3NO(g)
