RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Q.2 using the model of object analysis‚ analyse one fashion article. (Choose a garment‚ which can be used to discuss fashion from the point of view of the consumer. This garment must be able to demonstrate how the consumer individually constructs their identity and conveys that identity through the style and styling of clothing. You should treat this garment as an object as a form of evidence‚ which can help you to explain theories of fashion discussed in the sessions. The intention of your analysis

WHY DOES THE COLOUR LEAK OUT OF COOKED BEETROOT? PLAN Hypothesis Temperature has an effect on the leaking of the colour from beetroot. This means that as the temperature is altered there will be a change in the rate of colour leakage. Scientific Background Beetroot is a very familiar vegetable and is commonly known as beet. It is famous in most recipe books that advice that its outer skin is not to be removed to avoid getting red dye in the cooking water. If we look at the internal structure

natural‚ and truly aesthetic objects‚ it’s relatively easy to define each in their own ways. Cultural objects differ from natural objects in the sense that cultural objects have been placed in an artistic manner by‚ and for the human population‚ whereas natural objects are in the most basic term‚ objects placed by nature for no other external reason. For instance‚ a bed of rocks laying among a path‚ strewn out for an artistic affect is considered a cultural object‚ where bedrock randomly strewn

Learning-Model Instrument The Learning-Model Instrument (page 32 in the text)‚ identifies four domains of learning based on an individual’s preference for cognitive or affective learning – and preference for concrete or abstract experiences. The premise for the model is that learning comes from thinking (cognition/abstract) and experiencing for most of us (affect/concrete). The Affective –Cognitive dimension correlates with the issues of people vs. task – another way of measure learning

" Factors affecting the speed of sound in a medium" Type of the medium- The speed of sound is not always the same. Remember that sound is a vibration of kinetic energy passed from molecule to molecule. The closer the molecules are to each other and the tighter their bonds‚ the less time it takes for them to pass the sound to each other and the faster sound can travel. It is easier for sound waves to go through solids than through liquids because the molecules are closer together and more tightly

Investigating the 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
