and in 6.15 mo dm–3 HCl is 1.06 ± 0.03 dm mol–½. In concentrated hydrochloric acid [RuCl6]2– slowly and spontaneously reduces. The initial rate is proportional to the 0.6 power of the initial ruthenium concentration. The reduction process is complicated and appears to be catalysed by an unknown impurity in the concentrated acid.

盐酸是在反应物的浓度的一阶。在298.1 K时,二阶速率常数为(7.24±0.25)×10 –3 dm 3 mol –1 s –1和ΔH ‡ = 59.2±6.3 kJ mol –1和ΔS ‡ = –86.9 JK –1 mol –1。反应产物是[RuCl 6 ] 3-和
溴。反应进行到平衡[RuCl 6 ] 2 – + Br –⇌ [RuCl 6 ] 3- +½Br 2,其在298 K和6.15 mo dm –3 HCl中的常数是1.06±0.03 dm mol –½。在浓
盐酸[RuCl 6 ] 2中缓慢且自发地还原。初始速率与初始
钌浓度的0.6幂成正比。还原过程很复杂,并且似乎是由浓酸中的未知杂质催化的。
