[填空题]
1.Define standard enthalpy of formzda; j8 :+ozih5wk.ii atio4 esrm+km5 sa8n.
2.Draw a Hess diagram for the following reaction:
2$CO$(g)+$O_2$→$CO_2$(g)
Make sure to label all enthalpies of formation.
3.Refer to section 12 (Section 13- 2025 Syllabus) of the data booklet to calculate the enthalpy of reaction, ∆H$^ᶱ_r$, for:
2$CO$(g)+$O_2$→$CO_2$(g)
∆H$^ᶱ_r$=- kJ mol$^{-1}$
Important note: The section numbers mentioned in the video solution are specific to the 2024 syllabus.
You can refer to the question stem to find the section numbers for the 2025 syllabus.
