C 2H2 + O2 → 2H2O • 220 g 55 g (35 g Fe_20 g S_55 g FeS) 3. Do the reaction in a closed container or collect and measure the gas. • Exothermic physical change It is an endothermic change. Endothermic chemical change; Heat is required to break the mercury-oxygen bond. • In general, an increase in temperature increases reaction rate. It lowers the activation energy. • Water The solubility of NH4Cl in water increases with an increase in temperature.
