氫氣是一種清潔能源,氫氣的制取與儲(chǔ)存是氫能源利用領(lǐng)域的研究熱點(diǎn).已知:CH4(g)+H2O(g)═CO(g)+3【專家解說】:①CH4(g)+H2O(g)═CO(g)+3H2(g)

【專家解說】:①CH4(g)+H2O(g)═CO(g)+3H2(g)△H=206.2kmol-1
②CH4(g)+CO2(g)═2CO(g)+2H2(g)△H=247.4kJmol-1
據(jù)蓋斯定律,①×2-②得:CH4(g)+2H2O(g)═CO2(g)+4H2(g)△H=165.0kmol-1
故答案為:CH4(g)+2H2O(g)═CO2(g)+4H2(g)△H=165.0kmol-1.
