NEET Chemistry Chemical Equilibrium MCQ Question
Consider a closed system containing a gaseous reaction 2NO2(g) ⇌ N2O4(g) at equilibrium. A diagram shows a piston compressing the system, reducing the volume. Which of the following statements best describes the effect on the equilibrium position?
The equilibrium shifts to the right, favoring the formation of N2O4.
The equilibrium shifts to the left, increasing the concentration of NO2.
The equilibrium position remains unchanged as the reaction involves gases.
The equilibrium constant changes due to the change in pressure.
Correct Answer
Detailed Explanation
According to Le Chatelier's principle, increasing pressure by reducing volume favors the side with fewer gas moles. Here, 2 moles of NO2 form 1 mole of N2O4, shifting equilibrium to the right.
