Question
Ethanol can undergoes decomposition to form two sets of products.
C2H5OH (g) →
If the molar ratio of C2H4 to CH3CHO is 8 : 1 in a set of product gases, then the energy involved in the decomposition of 1 mole of ethanol is
C2H5OH (g) →
If the molar ratio of C2H4 to CH3CHO is 8 : 1 in a set of product gases, then the energy involved in the decomposition of 1 mole of ethanol is
Options
A.65.98kJ
B.48.137 kJ
C.48.46 kJ
D.57.22 kJ
Solution
ᐃr H = 
× 45.54 + 
× 68.91 = 48.137 kJ.
