Long Run Equilibrium (A) Firm and Industry: A competitive market is made up of a large number of firms with complete freedom of entry. Such firms together are called competitive industry. An industry can be defined as a group of firms producing homogeneous products with freedom of entry and exit and which earn only normal profits. Hence the concept of an industry is applicable only under competitive conditions. There is no fixed size of an industry though the analytical stability of an industry

TITLE Vapour Liquid Equilibrium OBJECTIVE To find the Vapour-Liquid Equilibrium (VLE) relationship for binary mixture and to plot the equilibrium curve. INTRODUCTION The term equilibrium is referred to as when a system is in a static condition and there is absolutely no changes that occur as time goes by. Vapour-liquid equilibrium is a condition where a liquid and its vapor are in equilibrium with each other‚ a condition or state where the rate of evaporation is equal to the rate of condensation

DISCUSSION Chemical equilibrium and its different applications were studied in this experiment. The Le Chatelier’s principle‚ which is the main principle behind chemical equilibrium‚ states that‚ “If an external stress is applied to a system at equilibrium‚ the system adjusts in such a way that the stree is partially offset as the system reaches a new equilibrium position.”[1] The “stress” can be a change in concentration‚ volume‚ pressure‚ or temperature that disturbs the equilibrium

chemical equilibrium is already achieved. A reaction is said to be at equilibrium when the following conditions exist. 1. 2. 3. Several factors such as temperature‚ concentration and pressure affects the rate of reaction which can cause an effect in the chemical equilibrium. A general rule is used to predict the direction in which an equilibrium reaction will move which is called the Le Chatelier’s Principle. It states that if an external stress is applied to a system at equilibrium‚ the system

The changes in cotton clothing market give us a good opportunity to illustrate the Principle of Market Equilibrium that any time there is an imbalance between supply and demand‚ economies will normally move toward an equilibrium in which no individual would be better off doing something else. In fact‚ we have now seen that a market tends to have a single price‚ the equilibrium price at which the quantity demanded of a good or service is equal to the quantity supplied. When the demand and/or

The First and Second Conditions for Equilibrium The first condition for equilibrium: The second condition for equilibrium: • • ΣF = 0 ΣΓ = 0 • In when both of these conditions are satisfied in static systems all forces and torques sum to zero. In problems where the first and second conditions of equilibrium are satisfied‚ the best strategy is to create FBD’s for both the first and second conditions‚ derive equations based on these FBD’s and then see what useful information may be gleaned from
