Determination of Rate and Order of a Reaction Results This experiment used a spectrometer to find the wavelength with maximum absorbance in a green food coloring solution. For this particular solution the wavelength was 629.7 nm. The system was then calibrated to that and was set to measure the food coloring and bleach solution. The measured visible light absorbance of the mixed solution was collected over a time of 200 seconds and eight points were then selected and placed into the Absorbance

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

Factors that affect exchange rates. Like any price‚ the exchange rate deviates from the cost basis - the purchasing power of currencies – under the influence of supply and demand of currency. The ratio of the supply and demand depends on several factors. It reflects connections with other economic categories - cost‚ price‚ money‚ interest‚ balance of payments‚ etc. There is a complex of interweaving and nomination of decisive factors. Among them are the following. • 1.The rate of inflation. The ratio

However‚ if people will let down the volume of sound‚ others would not be mannered by the increase in volume managing to the deadly heart attack. Sound within the community‚ for instance‚ traffic can cause a human’s heart rate of increase. Problem of heartbeat tends to be solved by seeing what kind of sound causes the increase of heart rates to place a termination to increase of heart rate. If

environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using

BUSINESS IMPLICATIONS OF EXCHANGE-RATE CHANGES BUSINESS IMPLICATIONS OF EXCHANGE-RATE CHANGES Market Decisions On the marketing side‚ exchange rates can affect demand for a company’s products at home and abroad. A country such as Mexico may force down the value of its currency if its exports become too expensive owing to relatively high inflation. Even though inflation would cause the peso value of the Mexican products to rise‚ the devaluation means that it takes less foreign currency to

REACTION PAPER Inflation Rate in the Philippines 2011 The Bangko Sentral ng Pilipinas (BSP) said that although the scope for keeping policy rates has narrowed due to continued climb of the inflation rate‚ there is still no need to hike rates. This as the government reported the rise in the inflation rate to 4.3 percent last February from month-ago’s 3.5 percent on account of faster inflation rate in food and oil commodities.
