参考答案：
已知合成氨反应N2(g)+3H2(g)
2NH3(g) ΔH="-92.20" kJ·mol-1,在某温度下2 L的密闭容器中进行,测得如下数据:
| 时间(h) 物质的量(mol) | 0 | 1 | 2 | 3 | 4 |
| N2 | 1.50 | n1 | 1.20 | n3 | n5 |
| H2 | 4.50 | 4.20 | 3.60 | n4 | n6 |
| NH3 | 0 | 0.20 | n2 | 1.00 | 1.00 |
下列说法正确的是（ ）
A.反应3 h内,反应速率v(N2)为0.17 mol·L-1·h-1
B.此温度下,该反应的平衡常数为0.037
C.反应进行到1 h时放出的热量为9.22 kJ
D.4 h时,若再加入1 mol N2,达到新的化学平衡时,N2的转化率是原来的两倍
