Answer 1

Answer #1

To get the required equation do the following operation,

(3) + (2)/2 - (1)

N₂O₃ (g) -----------> NO (g) + NO₂ (g)

Delta H_rxn = delta H₃ + (Delta H₂ / 2) - delta H₁

= 33.2 + (180.4 / 2) - 83.7

= + 39.7 kJ

Since change in enthalpy of the reaction is positive, it is an example of endothermic reaction.
