Chemical Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the

lack of job opening in our society. Even those who are fresh graduates in college are hard to get job‚ mostly those graduated in college are jobless and they are vacant only in their house. This is the reason why Philippines tackles unemployment rate in economic crisis. Once‚ there are job openings that need many options and requirements‚ so other people are not qualified of it and they may experience hard getting a job. Also‚ because of unemployment crisis here in Philippines‚ mostly Filipino

statement concerning risk premium? A. The greater the volatility of returns‚ the greater the risk premium. B. The lower the volatility of returns‚ the greater the risk premium. C. The lower the average rate of return‚ the greater the risk premium. D. The risk premium is not correlated to the average rate of return. 5. You bought 100 shares of stock at $20 each. At the end of the year‚ you received a total of $400 in dividends‚ and your stock was worth $2‚500 total. What was your total return

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the

One view is that the literacy rate has risen from 72% to 90% in the last 30 years. According to the 2005 Functional Literacy‚ Education‚ and Mass Media Survey conducted by the National Statistics Office (NSO)‚ 48.4 million or 84% of the estimated 57.6 million Filipinos who are 10 to 64 years old are said to be "functionally" literate (Source: "8 out of 10 Filipinos are functionally literate" by D. Pepito‚ TODAY newspaper‚ February 17‚ 2005). Functional literacy was found to be higher in females

Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

can be potentially more important for the next generation than it is for us. The issue is birth rate or population‚ what it is now and what it will be in the future. First of all‚ what is birth rate? The birth rate is the total number of births per 1000 of a population in a year. As you may know‚ by subtracting the death rate from the birth rate we will result in the rate of population. Here is a display of the birth rate from 1950 to 2015. Year Birth rate 19501955 37.2 19551960 35.3 19601965 34.9

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
