Some scientists have warned that the release of chlorofluorocarbons into atmosphere may impact : B. The ozone layer

many researches proven that chlorofluorocarbons may cause harmful effects to the ozone layer. After prolonged period of time, this will expose earth's organisms to direct UV, which will increase the risk of skin cancer

hope this helps

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
