What does one mean by exothermic and endothermic reactions? Give examples.
Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Example: C (g) + O2 (g) → CO2 + Heat Energy Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. Example - N2(G) + 02(G) - (Heat) 2NO
