QuestionHow does the equilibrium system adjust when cooled?
$2 \mathrm{NO}(\mathrm{g})+\mathrm{O}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}_{2}(\mathrm{~g})+113.06 \mathrm{~kJ}$
A. Shift right, decrease $\mathrm{NO}$ and $\mathrm{O}_{2}$ . B. No change in equilibrium. C. Shift left, increase $\mathrm{NO}_{2}$ . D. Shift left, increase $\mathrm{O}_{2}$ .

Studdy Solution
As the reaction shifts to the right, the concentrations of the reactants (NO and O2) will decrease, and the concentration of the product (NO2) will increase.
Therefore, the correct answer isA. The reaction will shift toward the products (right) and decrease the concentrations of $\mathrm{NO}$ and $\mathrm{}_{2}$ .
