Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

has relevance and meaning in the world today. Many people know the term describes the segregation laws that took place in the 1900’s‚ however that much is not the entire story. The term Jim Crow has roots in the deep south‚ and became so popular it was later used as a nickname to describe laws that dehumanized African Americans and striped them of their rights. “Jim Crow” has its roots in the 1830’s when a white minstrel performer‚ Thomas “Daddy” Rice‚ darkened his face with burnt cork and danced

Child Labor Laws In The 1800’s Child Labor‚ once known as the practice of employing young children in factories‚ now it’s used as a term for the employment of minors in general‚ especially in work that would interfere with their education or endanger their health. Throughout history and in all cultures children would work in the fields with their parents‚ or in the marketplace and young girls in the home until they were old enough to perform simple tasks. The use of child labor was not a problem

The purpose of this lab was to learn about Newton’s laws of motion by completing an experiment‚ to see how the forces act on objects. The independent variable of this experiment is the type and amount of materials used for the interior of the vehicle (out of the material list) and how they were used. The dependent variable is how and if the interior of the vehicle protected the egg from getting cracked. The controlled variables of this experiment were the height that the vehicle was dropped from

Newton`s Second Law – Lab Report Name: Tasneen Ahsan Date: 19th November‚ 2012 Purpose To show how the acceleration of an object changes when‚ the mass changes and the net force is kept constant and when the mass is the same.. Hypothesis I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude

“Law of Interaction” Law of Interaction “For every action‚ there is an equal and opposite reaction” The statement means that in every interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Interaction between the hammer and nail A hammer exerts a force on the nail and drives it into a board . But this is not the only force present for there must also be a force exerted on
