표준반응엔탈피 계산. Al2O3 + 3CO → 2Al + 3CO2

표준반응엔탈피 계산. Al2O3 + 3CO → 2Al + 3CO2

 

 

Use standard enthalpies of formation to determine ΔH°rxn for the reaction:

Al2O3(s) + 3CO(g) → 2Al(s) + 3CO2(g)

 

---------------------------------------------------

 

ΔHrxn = [생성물들의 ΔHf° 합] – [반응물들의 ΔHf° 합]

( 식 설명 https://ywpop.tistory.com/3431 )

 

= [2(0) + 3(-393.5)] - [(-1675.5) + 3(-110.5)]

= +826.5 kJ

 

 

답: +826.5 kJ
