Reaction Order and Rate Constant Units In some of our examples, the reaction orders in the rate law happen to be the same as the coefficients in the chemical equation for the reaction. This is merely a coincidence and very often not the case. Rate laws may exhibit fractional orders for ...

温度的影响在阿瑞尼士方程式(Arrhenius equation)里有被提及,一般而言,温度每上升10℃,反应速率会增为2~3倍。 (3) 浓度、压力及固体颗粒总表面积。 大多数的反应速率随着反应物浓度增加而上升,此现象也被研究归纳成为反应速率定律(rate law)。以碰撞学说解释浓度效应:当反应物的浓度上升时,所有反应物粒子的碰撞...
Step 2: Identify the powers of the reactants in the rate law.In the rate law:- The power of (A) is 12- The power of (B) is 2 Step 3: Sum the powers of the reactants to find the overall order of the reaction.The overall order of the reaction is the sum of the powers of...
Such a relation is called the “rate equation” or the “rate law”, which is expressed as aA + bB cC + dD n m ] B [ k[A] Rate [A] and [B] are the molar concentration of reactants A and B, respectively m is the orders of the reaction with respect to the attractant A n...
Going back to the rate law equation, it follows that a higher rate of constant results in a higher reaction rate. This makes sense because as temperature increases, molecules move faster and collide more frequently, resulting in an increased fraction of molecules with higher energy than the activ...
