So I have a school project where I will be investigating how the concentration of HCl (aq) affects the activation energy. I'm going to titrate (either with an indicator or thermometrically) it against a standard solution of NaOH (aq), how would I find the rate of reaction for each tria...
Question: What factors influence the rate of a reaction? How can we determine the rate law and orders of a reaction?In this investigation, you will measure the absorbance of a series of calibration standards to establish the relationship between absorbance (A) and concentration (c) for Blue#1...
y:y is the reaction order with respect to reactant B. k:k is the reaction rate constant. Its units are dependent on the reaction order. Next, we will see two examples of finding the rate law of a reaction from given rates data. In the first example, we will find a rate law for ...
In a research on how temperature affects the rate of a chemical reaction, if we increase the temperature by 10 degrees each time, what should we keep constant? A. The amount of reactants B. The shape of the container C. The color of the reactants D. The person who conducts the E....
In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a function of time. Once you have measurements at different times you can then plot these values and find the instantaneous rate of the reaction or the slope of the line. ...
In an experiment to study the effect of different catalysts on a reaction rate, how should variables be controlled? A. Use different reactants and different catalysts. B. Keep the reactants and the temperature the same. C. Change the pressure and the catalysts. D. Vary the amount of ...
And from what i can gather, i will have to plot a ln(rate) against a ln(concentration) graph. But how will that help me get a rate constant? What does the slope represent?Just to confirm, i find the rate of the reaction by measuring the change in concentration over the time taken ...
But here a thing to remember is that stress in itself is not hazardous. Rather, the danger is in the individual's reaction to the stress. 但有一点需要记住,压力本身并不危险。危险的是个体对压力的反应。 So psychologists have found that if we develop appropriate ways to cope with stressful sit...
•Light:Light of a given wavelength can speed up some reactions. •Temperature:Most reactions speed up with increasing temperature, and you're about to learn why. The Effect of Temperature on Rate of Reaction As a rule of thumb, a rise in temperature of 10 °C doubles the reaction rat...
The surface reaction is calculated using Arrhenius rate. The option for Mixing rate is blocked an turned grey in setup window. I found that "Rate of Reaction" is zero, "Kinetic Rate of Reaction" is a non-zero value, and "Turbulent Rate of Reaction" is zero, using "Report→Contours→Rea...
