Calculate the standard reaction entropy for the combustion of methane to carbon dioxide and liquid water...
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
A combustion reaction is describes as a carbon source reacting with oxygen and producing carbon dioxide and water. A common example of this reaction is methane reacting with oxygen gas in the following reaction: CH4(g) + 2O2 (g) yields CO2 (g) + 2H2O (g) What would the standard entropy change be, if 20 g of methane reacted with 20 g of oxygen? Answer: -1.626 J K-1
Predict the signs, comment and then calculate the enthalpy and entropy changes for the reaction of combustion ofmethane at 500 K. Will the reaction be spontaneous at 500 K? CH4(g) + 2 O2(g) → CO2(g) + 2H2O(g) We give: The enthalpies of formation of the products at 298.15 K in kJ/mol are: ∆Hf(CO2) = - 393.51; ∆Hf(H2O) = - 241.82; ∆Hf(CH4) = -74.81. The heat capacities at constant pressure in J.mol-1.K-1: Cp(CO2) = 37.11; Cp(H2O) = 33.58; Cp(CH4) = 35.31;...
Now 3 The combustion of octane to form carbon dioxide and liquid water can be written as: CH3(g) +2502(g) → 8C02(g) +9H, O(1) AH = -5450kJ mol-1 The combustion of octane to form carbon dioxide and water vapour can be written as: C2H18(8)+ 25 02(g) → 8C02()+9H, O(g) How would the energy released by the combustion of 1 mol of octane to form water vapour compare with the energy released by 1 mol of octane to form liquid water? 5
Methane, CH_4, reacts with excess oxygen to produce carbon dioxide and water. The standard molar enthalpy of combustion is -890.3 kJ. What is the change in enthalpy for the following reaction?

Combustion of hydrocarbons such as methane (CH4) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous methane into gaseous carbon dioxide and gaseous water. olo 10 ? 18 Ar...
When methane (CH4CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g)+O2(g)→CO2(g)+H2O(g)CH4(g)+O2(g)→CO2(g)+H2O(g) This type of reaction is referred to as a complete combustion reaction. Part A What mass of carbon dioxide is produced from the complete combustion of 1.80×10−3 gg of methane? Part B What mass of water is produced from the complete combustion of 1.80×10−3 gg of methane? Part C What mass of oxygen is needed for the...
