experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start

Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

LENDING RATES IN ZAMBIA The first thing that must be done in order to mitigating the problem of high bank lending rates is by reducing the gap between interest rate on Treasury bills and inflation. It must be borne in mind that the gap must not be reduced by increasing the level of inflation but by reducing the level of interest on TBs so that it comes close to that of inflation. The target will be to reduce the correlation of the relationship between interest rates on TBs and lending rates because

Growth rates and how to calculate them. Growth rates can be tricky to calculate and interpret and many people get confused. So here’s how to get ahead of everyone. Let’s start with a time series where we know the answer. In the example below‚ X starts at 100‚ grows 3%‚ then falls back again‚ then grows 3% again. So over the three years‚ it has grown from 100 to 103. 1 Year 2000 2001 2002 2003 Average CAGR 2 3 4 X Growth X DlnX 100 103 0.03 0.0295588 100 -0.0291262 -0.0295588 103 0.03 0.0295588

Interest rate is the rate paid by the debtor for using the money of creditor (http://www.investorwords.com/2539/interest_rate.html 1.12.2011.). Normally‚ the interest rate charged by percentage of the money borrowed for a period of one year. For example‚ debtor borrowed £100 from the bank for one year; the interest rate of that year is 10%‚ then the debtor has to pay £110 to the bank after one year for using their money‚ the extra £10 is the interest. Moreover‚ the interest rate played an important
