Homework Ch12 Thermodynamics What is a spontaneous reaction? A process that occurs without the need of extra energy, also is a system that releases Gibbs free energy. Indicate whether the following processes are spontaneous or nonspontaneous: a. Liquid water freezing at a temperature below its freezing point. Spontaneous, since there won't be extra energy required. b. Liquid water freezing at a temp above its freezing point. Nonspontaneous, There's no way liquid water can freeze at that temperature without the input of extra energy. c. The combustion of gasoline. Nonspontaneous since it requires an input of energy to start the combustion. d. A ball thrown into the air. Nonspontaneous because it needs an input of energy to compensate the force of gravity. e. A raindrop falling to the ground. Spontaneous, since gravity helps, there's not need of extra energy for this to happen. f. Iron rusting in a moist atmosphere. Spontaneous, there's no energy required.
