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

Different ways of looking at the world product different knowledge and thus different perspective come to be associated with their own concepts and theories. The concepts and theories of a particular perspective offer us with distinctive thinking tools with which tp craft ideas about organisations and organising.

Order in relation to the Social Contract Theory says that when the government abuses power‚ or the established order‚ the governed have to right to revolt: to overturn the established order‚ the established rules. Order is necessary but the question is at what cost is it necessary? Violence always accompanies revolts‚ but

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

In this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as

MAHATMA GANDHI vs. GENGHIS KHAN E.K ABSTRACT Leader is someone who has the ability to influence people on certain way. In order to become a leader‚ person has to have some skills or abilities. Through the history there many leaders with different characters‚ attributes‚ knowledge and skills. All of them had one common thing: they had ability to influence. Some leaders were better than the others‚ some left positive marks‚ some left negative ones and some left both of them. In this paper it

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

Case in the news: Demand/Supply and Equilibrium This article is based on the fundamental idea of supply and demand of the iPhone 5 whose demand has outstripped its supply. Due to the fact that the demand is so high‚ even those who pre-ordered the new slim iPhone 5 had to wait until October to get this new phone. The sales have broken all previous records and stand tall at 2 million phones in the first 24 hours. According to the article people had been
