We’re being asked to determine the ΔHf° for gaseous vinyl chloride, C2H3Cl(g).
Recall that the standard enthalpy of formation (ΔH˚f) refers to the enthalpy change for the formation of 1 mole of a compound from its elements in their standard states.
This means for C2H3Cl, the reaction involves the formation of 1 mole of C2H3Cl from H, C, and Cl in their standard states.
In their standard states, C exists as a solid, C(s), while H and Cl exist as a diatomic gas, H2(g) and Cl2(g).
The unbalanced reaction is:
C(s) + H2(s) + Cl2(g) → C2H3Cl (g)
Write reactions for which the enthalpy change will be
d. ΔHf° for gaseous vinyl chloride, C2H3Cl(g).
