is 66 seconds. At 600C‚ the time taken for the permanganate to decolorize is 10s. The higher temperature of the reaction‚ the faster the time taken for the permanganate to decolorize. This is because the higher temperature implies higher average kinetic energy of molecules and more collisions per unit time. The rate of effective collision increases‚ the rate of reaction increases. As a result‚ the time taken for reaction decreases when temperature increasing. The graph shows that 1/T is decreasing

The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules)‚ all of which are in constant‚ random motion. The rapidly moving particles constantly collide with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases‚ such as pressure‚ temperature‚ or volume‚ by considering their molecular composition and motion. Essentially‚ the theory posits that pressure is due not to static repulsion between molecules‚ as

CHEM 1112 Kinetics of the Persulfate – iodide Clock Reaction The purpose of this experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values

As these technologies were truly helpful and needed to the customers‚ gradually they became the de facto standards in the industries. By then‚ when the third party wanted to work with the users‚ they had to purchase the license; or for users who wanted more functions‚ they had to purchase full version of product.

Enzymes are naturally occurring biological catalysts that are extremely efficient and specific. Enzymes accelerate the rate of a reaction by factors of at least a million as compared to the same reaction without the enzyme. Most biological reaction rates are not perceivable in the absence of the enzyme. The term enzyme was first used by a German pshysiologist Wilhelm Kühne in 1897. There are over 700 different kinds of enzymes that have been identified. Enzymes can be classified into several categories

Use the knowledge of kinetics to explain each of the following statements. a. An increase in temperature at which a reaction takes place causes an increase in reaction rate . An increase in temperature means increasing the energy of the molecules present. If the molecules has more energy ‚ then more of the them will collide often with enough energy ‚ to overcome the activation energy barrier. causing the reaction to proceed more quickly. b.An addition of the catalyst increases the rate at which
