Definition:The order of reaction can be defined as the power dependence of rate on the concentration of all reactants. For example, the rate of a first-order reaction is dependent solely on the concentration of one species in the reaction. In order to determine the reaction order, the power...
1 A number of general questions concerning the mechanism of the reaction arise. 2.In contrast,the yield of reaction system 2 does not strongly depend on the temperature. 3.The size of the particles ranges from 7-8μm or larger. 4.Generally,improving the monomer purity is the key to get...
That will happen occasionally on the SAT, so don't get distracted by the extraneous information.Now that you have the value of rate constant k, crack question (2). In question (1), k=0.08, so if k triples, the new value for k is 0.08*3=0.24. According to the information in ...
or why is the rate of the reaction not uniform throughout? answer: this is because the rate of any reaction depends upon the reactant’s concentration at the given time. as the concentration of each reactant decreases with time, the rate of reaction also keeps changing. q2. can a ...
反应器的入口温度一般为480～520℃ Rallies the response is the strong endothermic reaction, in order to maintain the high reaction temperature and the reaction rate, uses generally three to four reactor series, between the reactor has the heating furnace to heat up raw material to the reaction ...
D. Chemicals that speed up the rate of chemical change are enzymes. Explanation Enzymes are biological catalysts that speed up the rate of chemical reactions in living organisms. They are proteins that act as catalysts by lowering the activation energy required for a chemical reaction to occur. ...

(过敏性的) reaction to the medicine when they first start chemotherapy,so it is important to give the medicine at a slower rate.Marie said that if we had a patient who reacted to the medicine,we should stop running the chemotherapy,check the patient's blood pressure,a...
Always uses electrons from only of the atoms involvedc. Uses all the electrons in all atoms involvedd. Uses the valence electrons of all the atoms involved• Which of the following would have the most dramatic effect in changing the reaction rate?a. Decreasing the temperature by two-foldb...
Q3. The reaction rate of a substance is directly proportional to its___. Answer: Active Mass The active mass is the concentration of the reacting substance in mol l-1. Hence, the rate of the reaction of the substance is directly proportional to its active mass. Q4. In the reaction rate...
