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

My second opinion on most important non-electronic product is books. Books are important because they give us insight into stories and lives we otherwise wouldn’t be able to experience. A book also can help with vocabulary and grammar. It helps us to build our spirit‚ give information‚ helps to pass time‚ make

experiment was to obtain some experimental measurement of Vapor Liquid Equilibrium for the Ethanol – Water system to verify the literature data. For this the Ethanol – Water system was heated to a certain temperature which is called the equilibrium temperature at atmospheric pressure and equilibrium temperature and compositions of vapor and liquid were measured. At the equilibrium temperature the samples of both vapor and liquid were taken in two different test-tube and the refractive index of both the

Stephany Matos Chem Lab: Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]/([Fe3+]•[SCN-] For this experiment we were able to determine the equilibrium constant KC for this reaction. First we prepared five different mixtures with known initial concentrations of

they must choose a path. “The step not taken” is a story about a man‚ who was at a crossroad and chose a path that he regretted soon after and continued to be haunted with guilt. The hero‚ Paul D’Angelo experienced an epiphany in his story “The step not taken”‚ where his subconscious acts as his benevolent guide. His journey will be analyzed through the archetypal theory‚ where the stages of monomyth will be used to explore his journey. In addition‚ examples of other characters in different literature

“Give me liberty or give me death” - Patrick Henry. These words are the essence of human life; without freedom is life lived in the darkest of caves. In the Colonists case‚ they are bound by a ruler who lives thousands of miles away‚ which is by no means a sufficient argument on waging war and breaking away from Britain‚ however‚ many offences have been made by the Mother country. In my opinion‚ colonists were justified because of taxation without representation‚ tyranny‚ and soiled relationship

The film “In Whose Honor” follows the activism of Charlene Teters‚ a brave Native American woman who fought for the respect of her culture. Teters made the move from Santa Fe‚ New Mexico to the University of Illinois after being recruited by their art department to add diversity (Rosenstein‚ 1997). Upon arrival‚ she was told to be quiet‚ get her degree‚ and attempt to ignore the mockery of her culture and spirituality (Rosenstein‚ 1997). Teters‚ raised in a traditional Native American community‚

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
