Step 1 — Evaluate each statement:

(A) Equilibrium is possible only in a closed system at a given temperature: ✓ Correct — equilibrium requires that no matter or energy escapes; only possible in a closed system at constant T.

(B) Both opposing processes occur at the same rate: ✓ Correct — this is the definition of dynamic equilibrium.

(C) When equilibrium is attained, the value of all its parameters became equal: ✗ Incorrect — at equilibrium, the rates of forward and backward reactions are equ
