concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles

Most everyone remembers a teacher who had an impact on her life. If you want to help‚ inspire and guide children‚ teaching is a profession that will give you the opportunities to make a difference. The road to becoming a teacher requires dedication‚ patience and a commitment. Today’s teacher does not receive a teaching certificate just because he has graduated with a Bachelor’s degree in education. To become a teacher in the United States‚ you must have a Bachelor’s degree in elementary‚ special

Information Age is a term that has been used to refer to the present economic era. The name alludes to the global economy’s shift in focus away from the production of physical goods (as exemplified by the industrial age) and toward the manipulation of information. Information technology The relatively recent field of information technology concerns the use of computer-based information systems to convert‚ store‚ protect‚ process‚ transmit and retrieve information. Technological advances in

of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview of the experiment: In this reaction two substances will be present in the solution

Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is

At first I wasn’t too surprised by the behavior of the Nacirema. Medicine men making potions and priests making sure water is holy are all things that I have heard about before. What really took me aback was the holy mouth man. I was shocked at the torture these people go through because of their beliefs in certain magic rituals. I’ve never had a cavity before‚ so just the thought of someone grinding holes in my teeth makes my mouth hurt. However‚ I guess if I was raised believing that these sort

MONEY SUPPLY A macroeconomic concept is the quantity of money available within the economy to purchase goods and services. Because (in principle) money is anything that can be used in settlement of a debt‚ there are varying measures of money supply. The narrowest measures count only those forms of money held for immediate transactions. In other words‚ if the money supply grows faster than real GDP‚ inflation must follow as velocity has been shown to be relatively stable. One of the principal
