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...
A rate law relates the concentration of the reactants to the reaction rate ina mathematical expression. It is written in the form rate = k[reactant1][reactant2], where k is a rate constant specific to the reaction. The concentrations of the reactants may be raised to an exponent (typi...
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. Pret...
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....
Rate of Reaction:The rate of reaction is simply how fast the reaction occurs. Some reactions, like explosions, are very fast. Other reactions, like the rusting of iron, are much slower. Several things can affect the rate of the reaction including the temperature, pressure, or pre...
Not only that, but what’s the impact on the response rate for the next satisfaction survey? This poor perception of surveys is what you’re up against. You want people to fill in your surveys, when pretty much every experience they’ve had of giving feedback has been frustrating. Think...
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 ...

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...
