7. Which of the following statements is incorrect?
(A) 2 NO(g) + 2 CO(g) → N₂(g) + 2 COz(g) is spontaneous at room temperature, then the reaction has △H >0.
(B) The reaction NH₃(g) + HCI(g)→  NH₄CI(s) can proceed spontaneously at room temperature, so the AH of the reaction is < 0.
(C) For the reaction MgCl₂(1)→ Mg(I) + Cl₂(g) to proceed at a certain temperature, it has △H > 0 and △S > 0.
(D) The reaction C(s) + CO₂(g)→2CO(g) cannot proceed spontaneously at room temperature, then the reaction has △H > 0.
(E) After the coating of copper-plated iron products is broken, the iron products are more likely to corrode than before the damage.
