Determination of a Rate Law and Temperature Dependence of a Rate Constant By Marvin Coleman March 7‚ 2011 Abstract: From the shown calculations & graphical analysis‚ the experimentally determined rate law is rate = K[I-].969 [H2O2].991 and the experimentally determined activation energy is 59.50 kJ/mole. Introduction: The rate of a reaction varies at different temperatures and reactant concentrations. In this experiment‚ the orders and dependence of the rate constant of the products

about thirty thousand Persian boys to “speak the Greek language and to use Macedonian weapon” [Plutarch]‚ the very same boys who would eventually be known as his ‘Successors’. Through these incidents‚ we can see that Alexander showed a strong determination to instill his ‘Policy of Fusion’ by going as far as to alter his lifestyle and his army. Many Macedonians were unhappy with his kind attitude towards the Persians though many had kept the resentment in the silence of their

Determination of specific heat Capacity of a solid by electrical method Introduction Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies‚ heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius‚ different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the

ON 1 Art Composition Perspective Beatriz Soto José María Vargas University COMPOSITION 2 Abstract The composition of art could be difficult and hard to identify. Therefore‚ a good composition of an image it is just there. The dictionary definition is as simple as “the action of putting things together” in some way it is correct. Nevertheless‚ the action of putting the elements together to call your attention‚ it is challenging to explain. An attractive painting grabs your attention from a distance
