Document Summary

Chemistry unit 6: module 3 solubility and chemical equilibrium iii. An ion which is part of the equilibrium is already present in the solution, and this impacts the equilibrium. An example of dynamic equilibrium that highlights the different chemical forms of nitrogen distributed throughout the atmosphere, hydrosphere, lithosphere and biosphere: atmosphere: nitrogen is commonly found as nitrogen gas. Nature naturally fixes nitrogen into ammonia, but not enough for our purposes this is why the haber- It involves a mixture of nitrogen and hydrogen gases forming an equilibrium with the ammonium product. Equilibrium constant for reaction is 4. 3 x 10-3 at 573k. It is an exothermic reaction (gives off heat: exothermic reactions have heat as a product (analogy, endothermic reactions have heat as a reactant (analogy) States that a system is in dynamic equilibrium it will respond to an external stress by relieving the stress in order to re- establish and equilibrium state.
