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 that

Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n Chemical

Which Liquid Dissolves Sugar Free LifeSavers Quickest? The purpose of my experiment is to find out which liquid‚(orange juice‚ water‚ Coca-Cola‚ or Sprite)‚ dissolves Sugar Free Life Savers the quickest.I think the Sprite will dissolve the Life Saver the quickest because it has the highest acidity‚ with ph levels reaching 2.4. The ph scale ranges from 0 to 14. Battery acid reaches 0 on the scale. 7 is considered neutral. Sprite has a ph level of 2.4. Coca-Cola has a ph level of 2.5. Orange juice

spending money on solutions to this consumption problem immediately. This is the biggest problem driving United States economy to inflation. It is proven by a fact that reducing the biggest consumption in the market would affect the aggregate demand graphs which would directly affect the economy negatively. So there should be other options to reduce the recession. Isn ’t it true that finding new energy sources to take the place of oil use would reduce this problem? High Oil Consumption in U.S.

The divorce rates have increased since the Divorce laws has been introduced in 1968‚ 20% of all divorces in Canada are a repeat divorce for atleast one of the spouses. With that‚ the divorce rate for first marriages is lower than the divorce rate for all other marriages. There were 27‚577 divorces in Ontario in 2001 and the statistics showed

Spot Rate and Forward Rate Spot Rate: It is nothing more than the YTM on bond. It is the rate of interest on bond maturing at any time in the future. It is also known as geometric average of 1 year forward rates in the future. Hence‚ YTM on bonds can be calculated as: When forward rates are given then; oS1 = oF1 oS2 = [(1+of1)(1+1F2)](1/2) -1 oS3 = [(1+of1)(1+1F2)(1+2F3)](1/3) -1 and so on. Forward Rates: It is the interest rate established today ‚ that will be paid on money to

What factors have led to increasing incarceration rates? How has this affected the United States economically and socially? Life‚ as we know it today‚ isn’t the way it was before because of the increase in incarceration rates within our nation; especially among our minority groups. When minority groups are mentioned‚ it’s aimed towards people that are different from the social majority. Incarceration is the state of being confined in prison; imprisoned. There are various factors that have led to

For this assignment‚ you will be designing a lab to investigate factors that affect the rate of a reaction. You are not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is
