Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

belief that the world we live in was stationary. They also believed that the earth was the center of the solar system. It wasn’t until the 1500’s that this theory was challenged. The time of scientific discovery was known as the scientific revolution. During this time‚ there were many improvements in science and experimentation. Old theories were being rejected by new laws that proved them wrong. As science improved‚ so did the world of philosophy. With science and philosophy discoveries‚ the arts began

RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials

Investigating the effect of temperature on plant cell membranes The purpose of this activity is: • to practise experimental and investigative skills • to investigate the effect of temperature on cell membrane structures Procedure SAFETY: Always carry scalpels clasped to a tile and with the tip pointing away from you. Beetroot cells contain pigments called betalains that give the tissue its dark purple-red colour. The pigment is contained in the cell vacuole. Investigation

Reaction Turbine Nithin Mannil 08d01001 Aim 1. To investigate the Torque/Speed and Power/Speed characteristics of Single Stage Reaction Turbine. 2. To determine the Isentropic Efficiency of a Turbine. 3. To compare the characteristics of a reaction turbine at different values of inlet pressure. 4. To compare the maximum shaft power vs pressure and isentropic efficiency vs pressure. Theory Turbines are machines which develop torque and shaft power as a result of momentum changes in the

The ideologies of political participation changed during 1815-1840 in areas such as voter participation‚ the candidates’ party involvement‚ and the advancement of political interest. The events that led to the reformation of political campaigning initiated with the extinction of the Federalist Party after the war of 1812 to the Elections of 1828 & 1840. The essence of political reformation was most distinctly shown through statistical data‚ political debates‚ newspaper excerpts‚ and subjective entries

Adolescence is the period of transition between childhoods to adulthood. It is a period when rapid physiological changes and demands for new social roles take place. The adolescents‚ due to these changes often face a number of crises and dilemmas. Adolescence is considered to start with the onset of puberty‚ which is as a period of transformation from a stage of reproductive immaturity to a stage of full reproductive competence. This period in the life span of a person makes them assume the ability
