JEE Main 2026 Chemistry question
Observe the following equilibrium in a 1 L flask. At , 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 to establish the equilibrium again. The new equilibrium concentrations (in M) of A and B are respectively.
Answer: (4)
Solution
. After adding 0.1 mol A: solving gives . Moles of A=0.557, moles of B=0.418.
