119.8 J of heat is evolved when 12 g of CO reacts with enough NO₂. ΔH=-119.8 J.
Step by step explanation:
Given that 4CO(g) + 2 NO2 → 4CO2(g) + N2 (g). ΔH = -1198 J , that is when 4 moles of CO reacts with NO₂ it releases 1198 Joules of energy.
That is of CO reacts with enough NO₂ to release 1198 J of Heat.
⇒ 1 gram of CO reacts with enough NO₂ to release of Heat.
Therefore, 12 grams of CO reacts with enough NO₂ to produce of heat.
ΔH =-119.8J as the heat is evolved when 12 g of CO reacts with enough NO₂
