Which statement best rationalizes ASsys for combustion of methane? CH4(g) + 2O2(g) → CO2(g) + 2H₂O(g) This is a combustion reaction so ASsys will be a large negative number. This is a combustion reaction so ASsys will be a large positive number. There are no changes of state and no change in Anxn so ASsys will be small. Combustion reactions are exothermic, so ASsys also will be a large negative number
