Consider the following reaction. Is this reaction exothermic or endothermic? exothermic endothermic Calculate the amount of heat transferred when of is decomposed by this reaction at constant pressure. amount of heat transferred: For a given sample of , the enthalpy change during the reaction is . What mass of methane gas is produced?
Expert Answer
The chemical reaction is Given the enthalpy of the reaction is + 252.8kJ. , so the reaction is endothermic.In an endothermic reaction, energy is absorbed.The energy of products is more than the reactants .So
