8. Use the data in the appendix to calculate the standard entropy change, ASo, for the combustion of 1 mole of methane, CH4(9) (note: all reactants and products are in the gaseous state. Provide the balanced equation for the combustion) (8 points).
The heat of combustion of CH4 is 890.4 kJ/mol and the heat capacity of H2O is 75.2 J/mol×K. Part A Find the volume of methane measured at 298 K and 1.91 atm required to convert 1.17 L of water at 298 K to water vapor at 373 K.

The combustion of methane (CH4) at 298.0 K produces carbon dioxide gas (CO2) and liquid water. A constant volume vessel of volume V = 0.807 L is loaded with 1.000 mole of each methane and oxygen. Find the total pressure in bar after the reaction has taken place at 298 K. Use an ICE box, and for now you may assume the reaction goes to completion at 298 K
Calculate the standard free energy change for the combustion of one mole of methane using the values for standard free energies of formation of the products and reactants. The sign of the standard free energy change allows chemists to predict if the reaction is spontaneous or not under standard conditions and whether it is product-favored or reactant-favored at equilibrium. kJ/ mol-rxn
A gaseous fuel mixture stored at 745 mmHg and 298 K contains only methane (CH4) and propane (C3H8). When 11.3 L of this fuel mixture is burned, it produces 760 kJ of heat. What is the mole fraction of methane in the mixture? (Assume that the water produced by the combustion is in the gaseous state.)

pre lab- heat of combustion (1-3D) Experiment 10 HEAT OF COMBUSTION Pre-Lab 1. The Law of Conservation of Energy can be applied to combustion processes where fuel + oxygen products + energy The total chemical energy associated with the reactants must be the same as the total chemical energy of the products when the heat of combustion is included. a) Underline the graph which best represents the relationship between the stored chemical energy of the reactants and products in a...
