敌草快
When the pH value was 7and 9, the mean activation energy(Ea)for hydrolysis of diquat was 21.33and25.89kJ·mol~(-1), respectively. The activation entropy(ΔS), which displayed striking relation, increased withthe increasing temperature, and the mean activation entropy was -191.83J·(mol·K)~(-1).
在pH为7和9的条件下，敌草快的水解活化能比较小，分别为21.33kJ·mol~(-1)和25.89kJ·mol~(-1)，而敌草快水解反应的活化熵的绝对值变化随温度升高而增加，表现出显著相关性，其平均活化熵为-191.83J·(mol·K)~(-1)。
