<h3>The enthalpy of the reaction : C.226.73 kJ</h3><h3>Further explanation</h3>
Delta H reaction (ΔH) is the amount of heat change between the system and its environment
(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)
The change in enthalpy in the formation of 1 mole of the elements is called enthalpy of formation
Delta H reaction (ΔH) is the difference between product enthalpy and reactant enthalpy (Hp-Hr)
Reaction :
2C + H2 -> C2H2
(ΔH) reaction = (ΔH) product - (ΔH) reactants
(ΔH) reaction = (ΔH) C2H2 - ((ΔH) C + (ΔH) H2)
for free element (ΔH) it has zero value, so (ΔH) C and (ΔH) H2 have zero value
From the available data: Hf (kJ / mol) C2 H2 (g)= 226.73
then
(ΔH) reaction = ΔH) C2H2 - ((ΔH) C + (ΔH) H2)
(ΔH) reaction = 226.73 - (0 + 0)
(ΔH) reaction = 226.73 (answer C)
