JEE Mains · Chemistry · STD 11 - 6.1. Equilibrium - 1 (chemical Equilibrium)
Observe the following equilibrium in a 1 L flask.
\(A(g) \rightleftharpoons B(g)\)
At T(K), the equilibrium concentrations of A and B are 0.5 M and 0.375 M respectively. 0.1 moles of A is added into the flask and heated to T(K) to establish the equilibrium again. The new equilibrium concentrations (in M) of A and B are respectively.
- A 0.367, 0.275
- B 0.53, 0.4
- C 0.742, 0.557
- D 0.557, 0.418
Answer & Solution
Correct Answer
(D) 0.557, 0.418
Step-by-step Solution
Detailed explanation
\(\begin{array}{ccc} A & \rightleftharpoons & B \\ 0.5 M & & 0.375 M \end{array} \quad\) (At equilibrium) \(K_{eq} = \frac{[B]_{eq}}{[A]_{eq}} = \frac{0.375}{0.5} = 0.75\) Now 0.1 mole of A is added so reaction will move in forward direction. \(A \rightleftharpoons B\)…
