NEET Chemistry Chemical Equilibrium MCQ Question
Which of the following statements about the equilibrium of the reaction PCl5 (g) ⇌ PCl3 (g) + Cl2 (g) is correct?
Increasing the temperature will favor the formation of PCl3 and Cl2.
Adding more PCl5 will shift the equilibrium to the right.
Increasing pressure will shift the equilibrium towards PCl5.
The equilibrium constant Kc remains unchanged with the addition of an inert gas.
Correct Answer
Detailed Explanation
Increasing temperature shifts the equilibrium in the endothermic direction, which favors the formation of PCl3 and Cl2. The equilibrium constant does not change with the addition of an inert gas, and adding more PCl5 shifts the equilibrium to the right, while increasing pressure favors the side with fewer gas moles.
