**Equilibrium Reaction and Temperature Effects**Consider the following equilibrium reaction and its enthalpy change ($ \Delta H^\circ $):\[ 2 \, \text{SO}_2 (g) + \text{O}_2 (g) \rightleftharpoons 2 \, \text{SO}_3 (g) \quad \Delta H^\circ = -198 \, \text{kJ} \]**Question**: Predict whether the reaction will shift towards the products or reactants with a decrease in the temperature.**Options**:- **a. Shift towards the reactants.**- **b. Shift towards the products.**- **c. The temperature change would have no effect.****Analysis**: The reaction is exothermic (releases heat), as indicated by the negative $\Delta H^\circ$. According to Le Chatelier's principle, a decrease in temperature will favor the formation of products in an exothermic reaction, thus shifting the equilibrium towards the products.

Consider the following equilibrium: 2NO₂ (g) N₂O₂(g) AG=-5.4 kJ Now suppose a reaction vessel is filled with 0.316 atm of nitrogen dioxide (NO₂) at 708. "C. Answer the following questions about this system: Under these conditions, will the pressure of NO₂ tend to rise or fall? Is it possible to reverse this tendency by adding N₂O₂? In other words, if you said the pressure of NO₂ will tend to rise, can that be changed to a tendency to fall by adding N₂O? Similarly, if you said the pressure of NO₂ will tend to fall, can that be changed to a tendency to rise by adding N₂O? If you said the tendency can be reversed in the second question, calculate the minimum pressure of N₂O₂ needed to reverse it. Round your answer to 2 significant digits. rise O fall O yes O no atm 0.8 X
