The decomposition of calcium carbonate, CaCO3(s)CaO(s)+CO2(g), has G=130J/mol at room temperature and does How many moles of calcium carbonate can be decomposed by the burning of 7.0mol of methane? not occur spontaneously. The reaction does Express your answer in moles. become spontaneous at very high temperatures, so it can be driven by being coupled to a combustion reaction that raises the temperature. For example, the combustion of methane, CH4+2O2CO2+2H2O, has G=818kJ/mol
