JEE Mains · Chemistry · STD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)
\(4.5\) moles each of hydrogen and iodine is heated in a sealed ten litre vessel. At equilibrium, \(3\) moles of HI were found. The equilibrium constant for \(H _2( g )+ I _2( g ) \rightleftharpoons 2 HI ( g )\) is .......
- A \(1\)
- B \(2\)
- C \(3\)
- D \(4\)
Answer & Solution
Correct Answer
(A) \(1\)
Step-by-step Solution
Detailed explanation
\(H _{2( g )}+ I _{2( g )} \rightleftharpoons 2 HI _{( g )}\) \(K _{ c }=\frac{[ HI ]^2}{\left[ H _2\right]\left[ I _2\right]}=\frac{(3)^2}{3 \times 3}=\frac{9}{9}=1\)
