    Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

    Abstract Equilibrium is the condition of a system in which competing influences are balanced. In the experiment we measured and experimented for the equilibrant force‚ conditions and center of gravity. Our results showed consideration as to disregarding other forces than weight and tension. 1. Introduction Equilibrium is a state of balance in which it is a condition where there is no change in the state of motion of a body. Equilibrium may be observed on objects which are at rest and also

    com/articles/2008/06/06/business/air.php The Principle of Market Equilibrium The equilibrium price is the price at which the quantity demanded of a good or service is equal to the quantity supplied. The Principle of Market Equilibrium states that perfectly competitive markets are always moving toward said equilibrium. If the price is too high or low‚ there will be a surplus or shortage‚ respectively‚ which will drive the price towards the “market-clearing” equilibrium price. When there is a shift of the demand and/or

    LONG-RUN EQUILIBRIUM OF A FIRM UNDER PERFECT COMPETITION In the long run‚ a firm in the perfectly competitive market can earn only normal profit. So‚ the profit maximization under long run is: (1)Necessary condition P=LMR=LAR=LMC=LAC (2)Sufficient condition Slope of MC > Slope of MR We can establish this condition from the following analysis. In the above diagram for any market price OP1 the existing firms can earn supernormal profit as for the equilibrium output level OQ1. The average
