CHEMICAL EQUILIBRIUM I. Introduction In a chemical reaction‚ when reactants are mixed together in a reaction vessel‚ the whole of the reactants do not get converted into products. After some time‚ there will come a point when a fixed amount of reactants will exist in harmony with a fixed amount of products; neither amount will change anymore. This state is called chemical equilibrium (Birk‚ 1994; Jones‚ 1987; LeMay‚ 2002). There are three characteristics of a system in chemical equilibrium: a. the

Torque and Equilibrium Purpose: Apply principle of static equilibrium to determine a coefficient of friction. Research Question: What is the coefficient of friction between a meter stick and wall? Hypothesis: Tying a piece of string on to the end of a meter stick‚ put the other end of the meter stick against the wall so that the meter stick is horizontal and does not slide down the wall. Hang a weight on the meter stick sliding it to a point where the meter stick is about to come off from the wall

The marketing strategy is supposed to show the long term direction and scope of the company with stakeholders and the environment in mind. In a fast changing industry there is a big challenge to create a long term strategy. There can be a lot of factors changing in the short run that cannot be foreseen. (Johnson‚ Scholes and Whittington‚ 2007). How should the company design their marketing strategy to be usable in the long run? There are different differentiation strategies for the company to choose

CHAPTER ONE 1. INTRODUCTION 1.1 BACKGROUND The problem of price escalation‚ especially in the construction industry‚ is a worldwide phenomenon‚ and its ripple is normally a source of friction between clients and contractors on the issue of price escalations. If this friction is not properly handled‚ this could stall the progress of work and may subsequently lead to project abandonment and the actual project will suffer with universal inflations of costs. [5]Although the causes of project

Chemical Equilibrium: Finding equilibrium constant‚ Kc 1 Abstract Chemical reactions are accompanied with formation of products. A reaction can be reversible or forward according to the rate of formation of product. However‚ they do not reach completion and the mixture remains in equilibrium. This theory help us the study the existence of equilibrium constant‚ Kc. This constant is temperature dependent‚ and it must be calculated at given temperature. This equilibrium constant
