True or False: Discussion 2-Thermodynamics 1. True or False: A reaction that is exothermic must be spontaneous. 2. True or False: A reaction that is spontaneous is known as endergonic. 3. True or False: Hess's law is true because enthalpy is a state function. Fill in the blank: 4. For a change that takes place at constant pressure, the heat char system is known as the change in 5. If a reaction is endothermic, but also spontaneous, what must the AS be?

Expert Solution
Step 1

Exothermic reaction :- A reaction that releases energy from the system in the form of heat. ( i.e ∆H = -ve) 

Endothermic reaction :-a reaction that a the system absorbs energy from its surroundings in the form of heat. ((∆H = +ve)
