Chemistry Question from JEE Main 2026 · 28 January, Shift 2

Observe the following equilibrium in a 1L1 \, \text{L} flask: A(g)B(g)\ce{A(g) <=> B(g)} At T(K)T(\text{K}), the equilibrium concentrations of A and B are 0.5M0.5 \, \text{M} and 0.375M0.375 \, \text{M} respectively. 0.10.1 moles of A is added into the flask and heated to T(K)T(\text{K}) to establish the equilibrium again. The new equilibrium concentrations (in M) of A and B are respectively:

  • A

    0.7420.742, 0.5570.557

  • B

    0.3670.367, 0.2750.275

  • C

    0.530.53, 0.40.4

  • D

    0.5570.557, 0.4180.418
