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...
1. A student investigated the factors that canaffect the reaction rate for the decompositionof hydrogen peroxide, using manganese( IV)oxide as a catalyst. He changed theconcentration of hydrogen peroxide andmeasured the volume of oxygen gas evolved in5 seconds.(a)State the independent variable and...
Rate of Chemical Reaction:The rate of a chemical reaction can be determined by the change in the concentration of product over a given period of time. There are different factors that can affect the rate of a chemical reaction.Answer and Explanation: ...

Mixing reactants increases their ability to interact, thus increasing the rate of a chemical reaction. Summary of Factors The chart below is a summary of the main factors that influence the reaction rate. There is typically a maximum effect, after which changing a factor will have no effect ...
Chemical Reaction To change the rate of a reaction one or more of the following things must happen: 1. Increase the number of collisions between the reactant particles 2. Increase the energy of the collisions. 3. Decrease the activation energy. This is all very well but how can we follow...
The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose, sucrose, lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakd...
