When a catalyst is added to a reaction at equilibrium, what happens to the equilibrium position? A. Shifts to the right B. Shifts to the left C. No change D. Can't determine 相关知识点: 试题来源: 解析 C。解析:催化剂只能改变反应速率,不能改变平衡状态,所以平衡位置不变。
23 For a reaction at equilibrium, which change can increase the rates of the forward and reverse reactions?(3)(1) a decrease in the concentration of the reactants(2) a decrease in the surface are a of the products(3) an increase in the temperature of the system(4) an increase in th...

当 vaporization rate=condensation rate时,平衡系统(equilibrium system)就建立起来了。 一些细节的强调 1)Kc是通过实验得出的经验值,通过实验测定只有温度会影响Kc值变化。 2)计算带入的是at equilibrium时物质的浓度或压强。引导学生用ICE table,把需要用于计算的量清晰地表达出来。 3)计算Kc时,不溶于水的物质与...
Equilibrium for a general reactiong) N
A. the rate of a chemical reaction B. the temperature of a chemical reaction C. the extent of a chemical reaction at equilibrium D. the pressure of a chemical reaction 相关知识点: 试题来源: 解析 C。解析:平衡常数 K 是衡量化学反应在平衡状态下的程度。A 选项是反应速率;B 选项是温度;D...
A. reactants B. products C. equilibrium state D. reverse reaction 相关知识点: 试题来源: 解析 B。平衡常数大说明反应更倾向于生成产物。选项 A“reactants”表示反应物;选项 B“products”表示产物;选项 C“equilibrium state”表示平衡状态;选项 D“reverse reaction”表示逆反应。所以答案是 B。反馈...
