it is known that the standard combustion enthalpy of methane is -882 kJ/mol
CH4 + 2 O2 --> CO2 + 2 H2O Hc = -882 kJ
based on hess's law, if a reaction is reversed, so does with the enthalpy
CO2 + 2 H2O --> CH4 + 2 O2 Hc = +882 kJ
which makes the reversed reaction become endothermic. if the system provides enough heat for the reaction (+882 kJ) to be absorbed, would the reaction just simply happen ?? or is there anything else to be considered ?
help me please……
