activation energy for the iodine clock reaction Introduction: The iodine clock reaction is a presentation of chemical kinetics‚ which are the elements that affect the rate of chemical reactions. When the two colorless solutions are incorporated together‚ no reaction can be spotted. But after a short period of time‚ the solution turns into a dark blue solution. The term rate of reaction is stated as the decrease in the concentration of one of the reactions or the increase in the concentration of

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

Harcourt-Essen Reaction Name: Manpreet Kaur Candidate Number: 7123 AS and A2 Aims: AS AIMS: 1. Investigate the effect of temperature on the rate of reaction. For this aim 3 sets of results will be obtained by timing how long it takes for the colour change to occur in different temperatures determined by the use of an electric water bath. With these results‚ the effect of temperature on the rate of reaction will be investigated. 2. Determine the

Malacanang has declared February 25 as a special holiday for all schools nationwide. People Power Day or Araw ng People Power is a school holiday. This is in commemoration of the 1986 People Power Revolution. Senator Gregorio Honasan‚ a former rebel soldier‚ was one of the major figures in the 1986 EDSA Revolution. As the anniversary of the 1986 EDSA revolution approaches‚ he thinks that there is no reason yet to "celebrate" its anniversary. For now‚ the Philippines can only "commemorate it." "Siguro

things about science and life during the activities and at the same time‚ we also had so much fun. We had a lot yet enjoyable activities during the Skymobile. First‚ we had the telescope viewing. They showed us the different parts of the telescope and discussed how each part functions in the telescope. Each of us was given a chance to view something using the telescope. I was really happy that time because it was the first time that I used a telescope. I just hope that it was done in the evening

Kinetics‚ A Clock Reaction Abstract The purpose for the experiment Chemical Kinetics‚ a clock reaction is to figure out the reaction rate of a solution regarding its concentration‚ temperature‚ and also determine the effects of when a catalyst is present. The experiment resulted that the concentration‚ as well as its temperature can affect the rate constant inversely the outcome of the rate constant. By conducting the experiment‚ it is also discovered that the rate order of the reaction resulted as
