NEET Chemistry Le Chatelier's Principle MCQ Question

Type: MCQ-diagram based-Medium-Class 11

In a diagram depicting the equilibrium shift for the reaction H2(g)+I2(g)2HI(g)H_2 (g) + I_2 (g) \rightleftharpoons 2HI(g), what effect would adding more I2I_2 have on the system according to Le Chatelier's Principle?

Question diagram
A

The equilibrium shifts to the right to produce more HIHI.

B

The equilibrium shifts to the left to produce more H2H_2.

C

The equilibrium remains unchanged as KcK_c is constant.

D

The reaction rate decreases due to increased pressure.

Correct Answer

Option A

Detailed Explanation

According to Le Chatelier's Principle, adding I2I_2 increases the concentration of a reactant, causing the equilibrium to shift to the right to form more HIHI, thereby counteracting the change.
