已知:2CO(g)+O 2 (g)=2CO 2 (g)△H=-566kJ/mol CH 4 (g)+2O 2 (g)=CO 2 (g)+2H 2 O(g)△H=-802kJ/mol H 2 O(g)=H 2 O(l)△H=-44KJ/mol 则CH 4 在空气中不完全燃烧时,热化学方程式是( )
A.
2CH 4 (g)+3.5O 2 (g)=CO 2 (g)+CO(g)+4H 2 O(g)△H=-1038kJ/mol
B.
4CH 4 (g)+7O 2 (g)=2CO 2 (g)+2CO(g)+8H 2 O(l)△H=-2642kJ/mol
C.
2CH 4 (g)+3.5O 2 (g)=CO 2 (g)+CO(g)+4H 2 O(g)△H=-1497kJ/mol
D.
2CH 4 (g)+3.5O 2 (g)=CO 2 (g)+CO(g)+4H 2 O(l)△H=-1497kJ/mol
