Question

Molar heat of combustion of ethyl alcohol at constant pressure and at 300K is

- 320 K.Cal. Calculate molar heat of combustion of ethyl alcohol at constant

volume.​

Answer 1

Explanation:

Heat of formation of ethanol = 2× heat of formation of CO

2

+ 3× heat of formation of water - heat of combustion of ethanol

Heat of formation of ethanol = 2∗(−94)+3∗(−68.4)−(−327) = −66.2kcal

Answer 2

Answer:

I Hope this is the correct answer
