Determining activation energy (Ea) of a reaction © KCl http://hk.geocities.com/fatherofchemistry Objective To determine the activation energy for the reduction of peroxodisulphate(VI) ions. S2O82-‚ by iodide ions I-‚ using a ’clock’ reaction. Principle The equation for reduction of S2O82- by I- is: S2O82- + 2I- → 2SO42- + I2 The formation of iodine is ’monitored’ by small & known amount of thiosulphate ions‚ S2O32-:

The Coverall Algorithm for Test Cases Reduction Preeyavis Pringsulaka Faculty of Science and Technology Assumption University Bangkok 10240‚ Thailand 617-372-5440 iampree@yahoo.com Abstract—This paper1 proposes a technique called Coverall algorithm‚ which is based on a conventional attempt to reduce cases that have to be tested for any given software. The approach utilizes the advantage of Regression Testing where fewer numbers of test cases would lessen time consumption of the testing as a whole

Experiment 5B: Ketone Reduction Objective: Using sodium borohydride as a reducing agent‚ the ketone 4-tert-butylcyclohexane is reduced to its corresponding alcohol. It is purified through extraction techniques to give the cis and trans diasteromer products. Procedure: The procedure was followed as outlined in Mayo’s book for Experiment 5B with the following modifications: 1. Reagents and Equipment – The reaction will be on a scale of 2X what is described in the text. 2. Reagents and Equipment

Title: Rate of transpiration I found interesting to know how different environmental factors affect the rate of transpiration. There are different environmental factors‚ such as light intensity‚ humidity‚ wind and temperature that affect the rate of transpiration. Transpiration is a topic 9 in our Biology higher level book. I have read all the information through this chapter and researched some extra information. Based on this information that I had known I decided to take experiment of environmental

Analysis Graph 1 interprets the data shown on the table of results. The graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active
