# What is the standard molar enthalpy of combustion of acetic (ethanoic acid)?

Jan 1, 2018

Unknown given no data.....

#### Explanation:

We assess the reaction....

${H}_{3} C - C {O}_{2} H \left(l\right) + 2 {O}_{2} \left(g\right) \rightarrow 2 C {O}_{2} \left(g\right) + 2 {H}_{2} O \left(l\right) + \Delta$

We could assess the reaction on the basis of $\Delta {H}_{f}^{\circ}$ if they were quoted...

$\Delta {H}_{\text{rxn"^@=Delta_f^@"products"-DeltaH_f^@"reactants}}$

...but we need data....
