about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction1 in EP6.4 and then in AA2.1. I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: Investigate the effect of concentration for each reactant and use the results to find the rate equation for this particular

The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist‚ the inside of your elbow‚ the side of your neck‚ or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for 10 seconds

energy needed for chemical reactions. The two main environmental factors that can affect the enzyme’s activity are temperature and pH‚ and each enzyme works best at a particular temperature and pH. The purpose of this enzyme kinetic experiment was to observe the effect of temperature and pH on the reaction of barley alpha-amylase enzyme with starch substrate and establish the optimum temperature and pH for this reaction. The optimum temperature and pH for the reaction of alpha-amylase and starch

Heart rate investigation Research statement: To investigate‚ how diabetes affect a person’s heart rate during physical exercise. Background information: Heart rate : Heart rate is the number of time a persons heartbeats per unit of time‚ usually measured in BPM (beats per minute). Heart rate is measured by finding the pulse on body‚ usually taken from carotid artery‚ which supplies blood to the head and the neck and radial artery‚ which Is located on your wrist below your thumb

1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

The society as a whole is worse off. This is because cash is the financial asset and it becomes is a liability of the government upon the time you found the cash. So‚ the taxpayers will have to make up for the government liability. 2. The average rate of return on investment in large stocks has outpaced that on investments in T-Bills by about 8% since 1926 in US. Why‚ then‚ does anyone invest in T-Bills? Answer: This is because T-bill is regarded as an almost risk free asset as it is backed

exchange rates‚ which is useful for international finance assignment. Exchange Rate is the price of one country’s currency in terms of another country’s currency; the rate at which two currencies are traded for another. It measures the number of units of one currency which exchange‚ in the foreign exchange market for one unit of another. Exchange rates are important because‚ they establish the relationships between the different currencies or monetary units of the world. Exchange rates have been

Interest Rates An interest rate is the rate at which interest is paid by borrowers for the use of money that they borrow from a lender. Specifically‚ the interest rate is a percent of principal paid a certain amount of times per period. Small companies often borrow capital from banks to buy new assets for its business‚ and in return the lender receives interest at a predetermined interest rate for deferring the use of funds and instead lending it to the borrower. Interest rates are
