Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing the equilibrium between PCl5, PCl3, and Cl2 in a closed container. Which of the following correctly describes the relationship between the equilibrium constant Kc and the concentrations of the reactants and products at equilibrium?
A
Kc = [PCl3][Cl2]/[PCl5]
B
Kc = [PCl5]/([PCl3][Cl2])
C
Kc = [PCl5][PCl3]/[Cl2]
D
Kc = [PCl3]/([Cl2][PCl5])
Correct Answer
Option A
Detailed Explanation
According to the equilibrium expression given in the NCERT context, Kc is defined as the concentration of products PCl3 and Cl2 divided by the concentration of the reactant PCl5.
