c. The reaction Br₂(→Br₂(g) has AH = 30.91 kJ/mol and AS = 93.3 J/mol-K. Use this information to show (within close agreement) that the boiling point of bromine is 332 K. d. People use propane as fuel for their barbecue grills. The combustion of propane is highly spontaneous at all temperatures. What keeps barbecue grills from catching fire the minute they are turned on?

Question 6: Gibbe Free Energy a. What is the Gibbs free energy at 298 K for the formation of methane: C(s) + 2H₂(g) → CH₂(g)? Where: AH=-74.85 kJ/mol AS-80.84 J/(mol-K) Is the reaction spontaneous at 298 K (room temperature)? ( b. When NaCl (table salt) dissolves in water, the reaction is endothermic. Yet, when added to water, it dissolves easily (spontaneously) without added energy. How can this be? (
