Question

4) Ethanol, C2H5OH, is mixed with gasoline and is sold as gasohol at many gas stations. C2H5OH (l) + 3O2(g) → 2CO2(g) +3H2O (g)

∆H = –1235 kJ

a. Determine the mass of ethanol that could produce 358 kJ of energy.

b. This reaction was found to be 71.0 % efficient. Calculate the mass of oxygen required to produce 56.0 g CO2 if it were present in 10.0 % excess.

c. Calculate the volume of O2 produced in question b at 0.900 atm and 87.0 °C.
