Gasohol is a mixture of gasoline and ethanol (grain alcohol), C2H5OH. Calculate the maximum work that could be obtained at 25 ºC and 1 atm by burning 2 mol of C2H5OH. C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(g)

Step 1
The enthalpy of formation (ΔHf) for CO2(g) is -393.5 kJ/mol and for H2O(g) is -241.8 kJ/mol. The ΔHf for C2H5OH(l) is -277.69 kJ/mol and for O2(g) is 0 kJ/mol (since it is in its standard state). The ΔH for the reaction can be calculated using the formula: ΔH = Show more…

Gasohol is a mixture of gasoline and ethanol (grain alcohol), $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$. Calculate the maximum work that could be obtained at $25^{\circ} \mathrm{C}$ and 1 atm by burning $1 \mathrm{~mol}$ of $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$. $$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(l)+3 \mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{CO}_{2}(g)+3 \mathrm{H}_{2} \mathrm{O}(g)$$
Gasohol is a mixture of ethanol and gasoline. Balance the equation, and determine the mass of $\mathrm{CO}_{2}$ produced from the combustion of 100.0 $\mathrm{g}$ of ethanol. $$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(1)+\mathrm{O}_{2}(\mathrm{g}) \rightarrow \mathrm{CO}_{2}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g})$$
