HOW FAST ARE CHEMICAL REACTIONS? THEORY The study of reaction rates‚ how fast or how slow a reaction takes place‚ is known as chemical kinetics. The rate of chemical reactions varies greatly. Some reactions‚ such as the explosion of an atom bomb are uncontrollable. Reactions like the decay of radioactive carbon (14C) are so slow that it takes centuries to see any noticeable change. Between the two extremes are reactions that can be measured in the laboratory. There are several factors that

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that

Detecting Signs of Chemical Change REAC 399 Prepared by: Elizabeth G. Perez Date of experiment: October 3‚ 2006 Course: Chemistry 100/60 Abstract: The objective of this experiment will be to combine various substances‚ liquids and metals‚ and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical. Introduction: An elements¡¦ reaction to certain substances may be predicted by its

1. Briefly explain the following: a. Chemical equilibrium- Chemical equilibrium is the state of a reaction when the concentrations of the reactants and products are no longer changing and remain constant. The forward reaction proceeds at the same rate as the reverse reactions making them equal. This type of equilibrium is also named dynamic equilibrium or a dynamic process. When a reaction has reached its chemical equilibrium‚ the constant K value will remain constant unless the temperature changes

Year 11 Module 1 – The Chemical Earth The Earth is made up of a large number of different substances: elements‚ compounds & mixtures We can classify elements & compounds as pure substances. These are always HOMOGENEOUS. Mixtures are not pure substances and can be either homogeneous or HETEROGENEOUS. Pure substances have a fixed composition eg copper metal‚ sulfur‚ carbon dioxide (CO2)‚ methane (CH4). Mixtures have variable composition and can also be separated into its components relatively

The Inhumane Weapons of Warfare Chemical warfare is a barbaric weapon of war that should be banned from any war situation. Chemical Warfare is using any chemical or chemical mix that can physically or mentally harm a human being. It has been killing people for over 2600 years and was created by Spartans. “They grabbed burning sulfur pitch and threw it over the walls of Athens attempting to fill the city with toxic gas.”[6] They tried this because they had a small army that was trying to take over
