I need help please ### Combustion of Propane QuizThe following question is designed to test your understanding of the combustion of propane and its effects on the system.#### Question:The combustion of propane is ______ (spontaneous/nonspontaneous) and results in the system becoming more ______ (ordered/disordered/no change in the system), and fits ______ (model a/model b/model c/none of the models) shown on the slide.#### Options:- [ ] spontaneous- [ ] nonspontaneous- [ ] no change in the system- [ ] none of the models- [ ] model C- [ ] ordered- [ ] disordered- [ ] model B- [ ] model AAnalyze the options and choose the correct answers based on your knowledge of chemical reactions and their spontaneity and effects on disorder in the system. **Components of ∆S⁰_univ for Spontaneous Reactions****Figure A:** Exothermic Reaction with a System that Becomes More Disordered- **ΔH_sys < 0:** The reaction is exothermic.- **ΔS_sys (Green bar):** Represents the entropy change in the system. It shows an increase in disorder.- **ΔS_surr (Green bar):** Represents the entropy change in the surroundings.- **ΔS_univ (Green bar):** Represents the total entropy change (universe).In an exothermic reaction where the system becomes more disordered, both the entropy of the system and the surroundings increase, leading to an overall increase in the entropy of the universe.**Figure B:** Exothermic Reaction with a System that Becomes More Ordered- **ΔH_sys < 0:** The reaction is exothermic.- **ΔS_sys (Pink bar):** Represents the entropy change in the system. It shows a decrease in disorder (more ordered).- **ΔS_surr (Green bar):** Represents the entropy change in the surroundings.- **ΔS_univ (Green bar):** Represents the total entropy change (universe).In an exothermic reaction where the system becomes more ordered, the decrease in systemic entropy is compensated by a larger increase in the surroundings' entropy, resulting in an overall increase in the entropy of the universe.**Figure C:** Endothermic Reaction with a System that Becomes More Disordered- **ΔH_sys > 0:** The reaction is endothermic.- **ΔS_sys (Green bar):** Represents the entropy change in the system. It shows an increase in disorder.- **ΔS_surr (Pink bar):** Represents the entropy change in the surroundings. It shows a decrease in surroundings' entropy.- **ΔS_univ (Green bar):** Represents the total entropy change (universe).In an endothermic reaction where the system becomes more disordered, the increase in systemic entropy outweighs the decrease in the surroundings' entropy, leading to an increase in the entropy of the universe.Each diagram highlights the interplay between the entropy changes in the system (ΔS_sys), the surroundings (ΔS_surr), and the universe (ΔS_univ) in different spontaneous reactions (exothermic vs. endothermic) and how the system's disorder influences the overall process.

A spontaneous reaction continues on its own once initiated. For such a reaction, is positive and…
