A, khi tăng áp suất của hệ, cân bằng chuyển dịch theo chiều làm giảm áp suất là chiều thuận, tạo ra nhiều NH3 hơn (tổng mol khí chất tham gia là 4, sản phẩm là 2, chiều giảm áp suất là về chiều có số mol khí nhỏ hơn). Khi thêm chất tham gia, cân bằng chuyển dịch theo chiều tạo thành sản phẩm (chiều thuận).

2. D. Giải thích như bên trên, khi giảm áp suất cân bằng chuyển dịch theo chiều tạo ra số mol khí nhiều hơn.

3. A. Cân bằng không bị ảnh hưởng bởi áp suất khi số mol khí hai vế bằng nhau.

4. C. Giảm nồng độ sản phẩm thì cân bằng chuyển dịch theo chiều làm tăng nồng độ sản phẩm (chiều thuận)
