Chemical equilibrium is a state where ___. A. the reaction has stopped B. the rates of the forward and reverse reactions are equal C. the concentrations of the reactants and products are always changing D. the reaction only occurs in one direction ...
A. The initial concentrations of the reactants were not accurately measured. B. The reaction system was not allowed enough time to reach equilibrium. C. There was an impurity in the reaction system that affected the reaction equilibrium. D. The method used to detect the concentration of the ...
When a chemical reaction is atequilibrium, the concentration of the reactants and the products remains the same over time. In other words, the forward and reverse chemical reaction are the same. Note: this does not mean the concentration of reactants and products is thesame. There is a la...
解析 C。化学平衡状态是动态的,因为正反应和逆反应仍在以相等的速率进行。选项 A“the reaction has stopped”反应停止错误;选项 B“the concentrations are always zero”浓度总是为零错误;选项 D“there are no more reactants left”没有反应物剩余错误。反馈 收藏 ...
