10. Given the themochemical equation for the combustion of methanol. 2 CH3OH(g) + 3 O2(g) ® 2 CO2(g) + 4 H2O(l) DrH = −1453 kJ/mol reaction d. Review the units “kJ/mol reaction”. What does “mole reaction” mean? e. If you produce 857 kJ of heat, how many “mole reactions” occurred? f. Relate the energy of the “mole reaction” to moles of methanol and determine the mass (in grams) of methanol needed.
Methanol, CH3OH (l), combusts according to the following equation: 2 CH3OH (l) + 3 O2 (g) → 2 CO2 (g) + 4 H2O (l) ∆rHo (298 K) = −1452 kJ Here is a list of Entropies of formation: S (J K-1 mol-1) at 298 K CH3OH (l) =126.8 O2 (g) = 205.14 CO2 (g) = 213.74 H2O = (l) 69.91 (a) If the above reaction was used in a fuel cell, say, to perform work, what will be the maximum...
Methanol (CH3OH) burns in air according to the equation 2CH3OH + 3O2 → 2CO2 + 4H2O If 167 g of methanol are used up in a combustion process, what is the mass of H2O produced
When methanol, CH3OH , is burned in the presence of oxygen gas, O2 , a large amount of heat energy is released. For this reason, it is often used as a fuel in high performance racing cars. The combustion of methanol has the balanced, thermochemical equation CH3OH ( g ) + 3/2 O2 ( g ) ⟶ CO2 ( g ) + 2H2O ( l ) Δ H = − 764 kJ How much methanol, in grams, must be burned...
