BRIGGS RAUSCHER OSCILLATING CLOCK COURSEWORK Aim: To investigate the effect of temperature on the rate of reaction. To investigate the order of reaction with respect to hydrogen peroxide and ethanoic acid (acetic acid) by the use of an oscillating clock reaction. To determine the activation enthalpy with and without catalytic ions and use this to compare the effectiveness. To investigate the rate equation‚ rate constant and possible mechanism for this reaction. Background research: The Briggs-Rauscher

increasing the concentration of KIO3‚ 0.15M concentrations resulted in times of 45.77 and 150.47 when tested twice which was unexpectedly higher than 13.68s at a concentration of 0.1 (Table 1). Similarly‚ raising the concentration of NaHSO3 decreased the clock period with the exception of the 0.2M concentration as it had the lowest time of 15.39s when 0.4M was expected to be lower (Table 2) These inconsistencies for the concentration data may have been due to measurement errors during the experimental process

If you value time then you will definitely buy those watches which you worth it. In 21st century Titan has made a product of innovative technology. Titan watches are a brand from Titan Industries which is a leading brand in India. Titan watches are very unique in its style ‚ design‚ fashionable‚ elegant and durable. These watches have a timekeeping technology of quartz crystals which is good for greater accuracy than the mechanical watches. It has a date and time‚ altimeter‚ barometer and compass

Lab #3: Method of Initial Rates: Iodine Clock Introduction The detailed system of steps in a reaction is called the reaction mechanism‚ and it is one of the principal aims of chemical kinetics to obtain information to aid in the elucidation of these mechanisms in order to better understand chemical processes. Reactions usually occur in a stepwise manner with each step proceeding at a different speed. If the rate of reaction is slow enough to measure‚ this is indicative of a step much slower

Main technology characteristics The following five characteristics of cloud computing are created by the Gartner Group‚ according to Plummer‚ et al. (2009) and Mell and Grance (2009)‚ and have a summariz-ing purpose for applying cloud computing in general (cited in Mora‚ 2009). Service based – The technology is service-oriented‚ thus abstracting the con-cerns of the consumer with the concerns of the providers (Mora‚ 2009). The ser-vices are provisioned automatically without human interaction
