The formation reactions for most organic compounds are hypothetical. For instance, carbon and hydrogen won't directly react to form methane (CH4), so that the standard enthalpy of formation cannot be measured directly. However the standard enthalpy of combustion is readily measurable using bomb calorimetry. The standard enthalpy of formation is then determined using Hess's law. The combustion of methane: WebWhich of the following are correct for micelle formation.
