The Rate of a Reaction The area of chemistry that deals with the rate or speed of chemical reactions is known a chemical kinetics. The word “kinetic” is derived from the Greek name kinitikos that means movement or motion. In the present context‚ the kinetic means the reaction rate or rate of a reaction that is defined as the change in concentration of a reactant or a product with time (M/s). Chemical reaction can be represented by the following general equation. Reactants Products It is very important

respiratory system. I predict that whilst carrying out the exercise‚ the breathing rate will considerably increase from resting to working breathing rate. However due to the fitness of the volunteer this breathing rate could be different. As soon as the volunteer has stopped the exercise‚ I predict that the breathing rate will steadily decrease over a number of minutes until it gets back to resting breathing rate. I can justify my prediction as throughout the exercise the oxygen requirement will

Floating Exchange Rate Exchange rates between currencies have been highly unstable since the collapse of the Bretton Woods system of fixed exchange rates‚ which lasted from 1946 to 1973. Under the "floating" exchange rates‚ since 1973‚ exchange rates are determined by people buying and selling currencies in the foreign-exchange markets . The instability of floating rates has surprised and disappointed many economists and businessmen‚ who had not expected them to create so much uncertainty.

Pulse Rate and Blood Pressure Purpose: To determine the effect of jogging on pulse rate and blood pressure. Hypothesis: If you jog then your heart rate and blood pressure will increase. Materials: Tape Measure Blood Pressure Cuff Procedure: 1. Record resting blood pressure and heart rate. 2. Measure out 100m. 3. Jog 100m (same speed every time) 4. When finished jogging 100m record heart rate and blood pressure. 5. Repeat steps 3&4‚ 3 more times 6. Calculate average heart rate and blood

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

An exchange-rate regime is the way an authority manages its currency in relation to other currencies and the foreign exchange market. It is closely related to monetary policy and the two are generally dependent on many of the same factors. The basic types are 1.

Flat Taxation is Equal Taxation Tax rates in America have been changed and reformed to try and meet the needs of the current economy‚ or to make a politicians look good. Recent questions have been asked about whether we should reform the entire style of tax rates in America. Future generations are going to feel the burden or benefit from tax choices we make now because it takes time for things of this magnitude to take place. Also it is a possibility that the future generation may need new tax
