Write the balanced overall equation (equation 3) for the

QUESTION:

Write the balanced overall equation for the following process (equation 3), calculate \(\Delta H_{\text {overall }}\), and match the number of each equation with the letter of the appropriate arrow in Figure P6.46:

(1) \(\mathrm{N}_2(g)+\mathrm{O}_2(g)\ \longrightarrow\ 2\mathrm{NO}(g)\)                           \(Delta H=180.6\mathrm{\ kJ}\)

(2) \(2\mathrm{NO}(g)+\mathrm{O}_2(g)\ \longrightarrow\ 2\mathrm{NO}_2(g)\)                      \(\Delta H=-114.2\mathrm{\ kJ}\)

____________________________________________________________________________

(3)                                                                               \(\Delta H_{\text{overall }}\ =\ ?\)

Delta H_overall

N_2 (g) + O_2 (g) rightarrow 2NO(g)

Delta H = 180.6 kJ

2NO(g) + O_(g) rightarrow 2NO_2 (g)

Delta H = -114.2 kJ
