下面划线字注音完全正确的一组是（    ）

下面为人体血液循环两条途径的示意图，据图作答：

下列说法正确的是                                                 （   ）
（1）增加水的量或温度，可以加快镁跟水的反应速率。
（2）增加硫酸的浓度，一定可以加快锌与硫酸反应制取氢气的速率
（3）对于反应CaCO₃(s) CaO(s) + CO₂(g)，增加CaCO₃的量，可以加快正反应速率，而增加CaO或CO₂的浓度，则可以加快逆反应速率
（4）对反应3H₂(g) + N₂(g) 2NH₃(g)，在密闭容器中进行(固定体积)，充入氦气，压强增大，则化学反应速率加快
（5）对于反应3H₂(g) + N₂(g) 2NH₃(g)，使用正催化剂，正逆反应速率同等程度加快。
