WebDec 31, 2016 · The standard enthalpy of combustion is the enthalpy associated with the combustion of one mole of substance under standard conditions. And thus for ethane it is the enthalpy associated with the following reaction: C2H 6(g) + 7 2O2(g) → 2CO2(g) +3H 2O(l) + Δ. My old notes say ΔH ∘ combustion = −1560 ⋅ kJ ⋅ mol−1. WebMethane – Thermal Conductivity. Thermal conductivity of Methane is 0.034 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction.
