**Problem 7.59****Chemical Reaction Overview:**Oxygen can be converted into ozone through the action of lightning or electric sparks. The reaction is as follows:\[ 3\text{O}_2(\text{g}) \rightleftharpoons 2\text{O}_3(\text{g}) \]For this reaction, the enthalpy change (\( \Delta H \)) is \( +68 \) kcal/mol (\( +285 \) kJ/mol), and the equilibrium constant (\( K \)) is \( 2.68 \times 10^{-29} \) at \( 25^\circ \text{C} \).**Part A: Thermodynamics**- Question: Is the reaction exothermic or endothermic?- Options: - Exothermic - Endothermic- Action: Select the appropriate radio button and click "Submit."**Part B: Equilibrium Favorability**- Question: Are the reactants or the products favored at equilibrium?- Options: - Reactants - Products- Action: Select the appropriate radio button and click "Submit."**Part C: Equilibrium Factors**Explain the effect on the equilibrium of the following changes:1.

For instance, at 18,000 feet, you would obtain 29% less oxygen than you would at sea level, which means that less oxygen is diffused into the blood from the lungs. This can lead to altitude sickness, or hypoxia, as it is called.Imagine a mountain climber who lives at sea level, trying to climb Mount Kilimanjaro for the first time. The climber is very experienced, so he plans to summit the 19,341-foot peak in four days, though it usually takes first-time climbers five or six days. Use your knowledge of equilibrium to describe the climber's reactions to this shortage of oxygen from the medical needs story line.**Match the equations to the appropriate blanks in the sentences. Make certain each sentence is complete before submitting your answer.***View Available Hint(s)*Options:- equilibrium shifts to O₂ release- equilibrium shifts to HbO₂ formation1. When the climber ascends the mountain without acclimating, __________ and the amount of HbO₂ in the blood decreases. 2. As the climber rests at a basecamp, the body increases the production of hemoglobin (Hb), __________ increasing the amount of HbO₂ in the blood.3. When the climber returns to sea level before reacclimating, __________ and the amount of HbO₂ in the blood increases initially.4. When the climber has reacclimated to sea-level conditions, the body produces less Hb, __________ and the amount of HbO₂ returns to normal 'sea-level' levels.*Buttons for interaction: Submit, Reset, Help* There are no graphs or diagrams in this image.
