reaction and the rate of the reverse reaction equal each other. At this point‚ the concentrations do not change with time. These reactions are said to be in equilibrium. Equilibrium is depended on a particular temperature‚ and the concentrations of reactants and products have to follow a rule demonstrated by the equilibrium constant Kc. The equilibrium concentrations that will be studied is the reaction between iron (III) ion and thiocyanate ion: The mixture of Fe3+ and SCN- react to form a compound

In this essay I am going to evaluate the statement if “the unintended consequences of minimum prices often far outweigh the benefits of imposing them”. After having read many articles about these it becomes clear to me that minimum wages have both positives and negatives to all the parties concerned in this issue. For the employers (“A legal entity that controls and directs a servant or worker under an express or implied contract of employment and pays (or is obligated to pay) him or her salary or

Economics April 16‚ 2012 n Price Controls: How efficient are price ceilings and price floors? If you think one is better than the other‚ make sure to bring up examples from our economy to validate your stand. Price ceilings and price floors are essential aspects of our economy. Price ceilings are government enacted laws preventing suppliers from establishing prices of key resources higher than a certain price‚ which is set by the government. Price floors are price minimums that can be charged

February 25‚ 2013 Lab: Equilibrium of Forces Purpose/Objective: The objective of this lab was to test the first condition of equilibrium for a set of concurrent coplanar forces‚ prove Lami’s Theorem‚ and to determine an unknown mass using rules of equilibrium. Procedure: In the lab‚ we wanted to find at what angles three separate weights would create a net zero force on a force table so that the ring holding the weights was exactly centered in the middle

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a

Equilibrium Movie Assignment November 23‚ 2013 Name: Caroline Garcia 1. Libria represents a dystopian society because it involves bad and terror. Dystopia is created in Libria when both feelings and expressions are outlawed and to keep that from being outlawed‚ the people must take injections of Prozium to control their emotions. Some examples from the movie include: - People with feelings are caught by Cleric’s (Preston and Partridge). Once they have been caught they are known as sense

Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application
