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

Lab O6 – Equilibrium Lab Application Purpose: An introduction to the qualitative aspects of chemical equilibrium. Starting with a reaction at equilibrium‚ one will change the concentration of various ions present in the equilibrium‚ and record the states of the changing equilibrium through observation. Theory: Equilibrium- the point at which a solution has become perfectly saturated; when their forward and reverse reaction rates are equal Concentration- a measurement of how much solute

Chemical equilibrium is the point at which the concentrations of reactants and products do not change with time. It would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD

When estimating the effect of changes in the money supply to changes in nominal GDP‚ it is common to assume that the velocity of money is constant. The velocity of money is a measure of average number of times per year that a dollar is exchanged. The quantity theory of money states that the money supply multiplied by the velocity of money is equal to the price level multiplied by output. ( ) Price level multiplied by output is the nominal output. Therefore‚ a percent change in the money

FRS 15 ‘Tangible fixed assets‘ FRS 15 was issued in February 1999 and sets out the principles of accounting for tangible fixed assets‚ with the exception of investment properties. The objective of the FRS is to ensure that tangible fixed assets are accounted for on a consistent basis. Fixed assets are held in our company for the profit of their use not from their resale. Tangible fixed assets should be capitalized when they are ready for use‚ which means when its physical completion is complete
