NEET Chemistry Chemical Equilibrium MCQ Question
Type: MCQ-numerical-Easy-Class 11
For the reaction H2(g) + I2(g) ⇌ 2HI(g), if the equilibrium concentrations are [H2] = 0.5 M, [I2] = 0.5 M, and [HI] = 1.0 M, what is the equilibrium constant Kc?
A
2.0
B
4.0
C
1.0
D
0.5
Correct Answer
Option B
Detailed Explanation
The equilibrium constant Kc is given by Kc = [HI]^2 / ([H2][I2]). Substituting the given concentrations: Kc = (1.0)^2 / (0.5 * 0.5) = 4.0.
