Without doing any calculations, match the following thermodynamic properties with their appropriate numerical sign (shown in image below) for part A-C.A) exothermic reaction C2H4(g) + H2O(g)----->CH3CH2OH(g)B) exothermic reaction 2NH3(g) + 3N2O(g)--->4N2(g) + 3H2O(g)C) endothermic reaction N2(g) + 2O2(g)----->2NO2(g)
