The Gibbs free energy describes the spontaneity of the chemical reaction. The reaction involving nitroglycerine is spontaneous.
Spontaneity is the condition of the reaction that continuously makes the product without adding input energy again and again. It is determined by the Gibbs free energy of the system.
When the Gibbs free energy of the thermodynamic system is negative then the reaction is said to be exothermic and is a spontaneous reaction. The negative Gibbs free energy of nitroglycerine at 273 K shows spontaneity.
Therefore, the reaction is spontaneous.
