Introduction The purpose of this experiment is to determine the rate equation for the “Iodine Clock Reaction” experiment. The experiment will consider the equations 〖2I〗^-+S_2 O_8→2〖〖SO〗_4〗^(2-)+I_2 and I_2+2〖S_2 O_3〗^(2-)→2I^-+S_4 O_6 in order to determine the rate law of Rate=k[〖〖S_2 O_8〗^(2-)]〗^a 〖[I^-]〗^b by using the experimental data to calculate the values of exponents a and b as well as the rate constant k.

equivalent to the sum of the voltage drops in that loop. In other words‚ the algebraic sum of the voltages (Vk) in a closed loop is equal to zero (Eq 2). (Eq 2) Equations (1) and (2) are interrelated‚ and this can be demonstrated through modeling a basic electrical circuit involving a second order‚ linear differential equation. For our basic circuit‚ we will use a single closed loop involving one voltage source‚ one resistor‚ one capacitor‚ and one inductor. First‚ it is important to establish

points chosen from all the data collected over the entire 200 seconds. As with the chart‚ it can be seen in the Absorption vs. time graph that light absorbed in the food coloring over time decreases. To find the concentration of the solution the equation for Beer’s law was used. Knowing A‚ є‚ and b‚ it was possible to solve for c and graph the points in the Concentration vs. time graph. This graph shows that over time the concentration of the food coloring is decreasing in the bleach. This function

word FLUX roughly means FLOW. So based on this idea we can define the ELECTRIC FLUX as the ELECTRIC FEILD through a SURFACE AREA. Since the area vector is defined as perpendicular to the surface and the electric field goes through it‚ we define this equation as a dot product‚ similar to the work function. Φ E = E • A = EA cos θ dΦ = ∫ Eda A differential amount of flux is the cross product between the electric field and a differential amount of area. Since you want the total flux‚ you integrate to

ABSTRACT The basic concept and operation of subsonic wind tunnel was demonstrated in this experiment by conducting airfoil drag analysis on a NACA 0015 airfoil. The small subsonic wind tunnel along with apparatus such as‚ the manometer rake‚ the inclined manometer and the pitot - static tube were used with different baffle settings to record varying pressure readings. To achieve this objective‚ some assumptions were made for the lower range of subsonic flow to simplify the overall analysis. From

beginning of a reaction are present at the end of the reaction—they have just been rearranged to bond differently and form new substances. It is important that chemical equations represent this law by always having equal numbers of each type of atom on both sides of the equation; chemists call this “balanced.” In a balanced equation‚ each type of element must appear on both sides of the arrow the same number of times. Sometimes it can be difficult to observe what happens to all of the atoms in a chemical
