Statement 1: For the reaction A(g) ⇌ B(g), if some A is removed from the system at equilibrium, the moles of B at the new equilibrium are less than the moles of B at the old equilibrium.
Statement 2: On removing A, the reaction shifts backward to make up A, which uses up B.

Question

Statement 1: For the reaction A(g) ⇌ B(g), if some A is removed from the system at equilibrium, the moles of B at the new equilibrium are less than the moles of B at the old equilibrium.

Statement 2: On removing A, the reaction shifts backward to make up A, which uses up B.

TestHub · Accepted Answer

Removal of A makes Q = [B]/[A] > K c The reaction moves in the backward direction, B ⟶ A, to restore the ratio This uses up B, so B at the new equilibrium is less than the old amount and Statement 1 is correct Statement 2 states this shift and is the reason for Statement 1 Both are correct and II is the explanation, option (a).
