Could someone help me breakdown this problem and figure out how to calculate it? I have added the balanced equation and broke down the products from the reactants. I have also looked up the thermodynamic data.
You are comparing the efficiencies of propane (C3H8) gas and ethanol (C2H5OH) as fuels. Assume all reactants and products are in the gas state.
I have the balanced equation for C3H8 and C2H5OH as C3H8 +5O2------>3CO2 + 4H2O
For the products, I have 3CO2 and 4H20
For the reactants, I have C3H8 and 5O2
The thermodynamic data that I found is as follows:
C3H8= -103.9 kj/mol
O2 = 0
CO2= -393.5 kj/mol
H2O= -285.8 kj/mol
a. Calculate the kj produced by burning 1 gram of each compound.
b. Calculate which compound produces more energy per mole of carbon dioxide produced in combustion.

Propane (C3H8)burns according to the following balanced equation: C3H8(g)+5O2(g)→3CO2(g)+4H2O(g) Calculate ΔH∘rxnΔ for this reaction using standard enthalpies of formation. (The standard enthalpy of formation of gaseous propane is -103.9 kJ/molkJ/mol.) Express the enthalpy in kilojoules to four significant figures.
I need someone to show me how to solve thus problem, I think I have the right idea, but I may be plugging in something wrong. What is ΔS° at 298 K for the following reaction? Fe2O3(s)+ 3CO(g)→ 3CO2(g) + 2Fe(s) Substance ΔG°f(kJ/mol) ΔH°f(kJ/mol) Fe2O3(s). -741.0 -822.2 CO(g) -137.2 -110.5 CO2(g) -394.4 -393.5 Thanks

The general form of a chemical reaction is aA + bB = cC +dD Where A and B are reactants in the forward direction and C and D are products in the forward direction. The lower case letters are the stoichiometric coefficients for the balanced equation. The general form of the equilibrium constant equation is then: Keq = [C]c[D]d/[A]a[B]b Part I: Q vs. K Q: reaction quotient can be calculated for a reaction at any concentration values of reactants and...
