WebThe standard molar enthalpy of formation of methane is negative 74.8 kilojoules per mole. So we're multiplying one mole by negative 74.8 kilojoules per mole. Our other reactant is … WebThe standard molar enthalpy of formation of methane is negative 74.8 kilojoules per mole. So we're multiplying one mole by negative 74.8 kilojoules per mole. Our other reactant is oxygen. And we know that diatomic oxygen gas has a standard enthalpy of formation of zero. So we could go ahead and write this in just to show it.

WebA negative sign is used with rates of change of reactants and a positive sign with those of products, ensuring that the reaction rate is always a positive quantity. In most cases, concentration is measured in moles per liter and time in seconds, resulting in units of M/s for the reaction rate. Created by Jay.
