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

Lab#: 15 Title: Exercise/pulse rate Aim: To investigate the effect of exercise on the pulse rate Materials/ Apparatus: Stop watch Diagram: Procedure: 1. The three middle fingers were placed just behind the bottom of the wrist as indicated in the diagram in order to see if the pulse could be felt. 2. (a) If the pulse was not felt the three fingers were moved about until it could be felt. (b) Changing the hand also helped to find the pulse. 3. The number of pulsation

The thesis statement or main claim must be debatable An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words‚ the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people. Example of a non-debatable thesis statement: Pollution is bad for the environment. This thesis statement is not debatable

Rate/Volume Analysis The following table presents the extent to which changes in interest rates and changes in the volume of interest-earning assets and interest-bearing liabilities have affected our interest income and interest expense during the periods indicated. Information is provided in each category with respect to (1) the changes attributable to changes in volume (changes in volume multiplied by prior rate)‚ (2) the changes attributable to changes in rate (changes in rate multiplied by prior

Homeostasis and how the body responds to exercise. This report will interpret the results of the practical activities that was done in order to monitor the changes in heart rate‚ temperature and blood pressure before and after exercise. Blood pressure is the measure of how much pressure is put on the walls of the blood vessels when the blood is pumped through them. This is measured in two parts‚ the larger number on top is known as the systolic pressure‚ this measures the pressure as the blood

The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate of consumption of A = -[pic]rate of
