Enzymes the Speed of Reaction Abstract This experiment tested the effects of pH on enzyme activity and how the concentration of enzyme affects the rate of reaction. Enzymes, biological catalysts, are sensitive to changes that can affect the rate of the chemical reaction. The specific enzyme used in this lab was Catecholase, an enzyme found in the cells of many fruits and vegetables. In the first exercise, the greatest amount of product was produced at a pH of 6, which was the most effective pH on. Investigation of the Effect of Caffeine on Human Reaction Speed Introduction This lab report will be exploring whether or not human simple reaction speed is affected by the consumption of around ml of a caffeinated beverage. This report will also assess whether or not there is any correlation between regular caffeine consumers, and a change in reaction time. This experiment, even though had ought to produce inaccurate data due to the lack of control variables, proved to be worthwhile as the. How does surface area affect reaction speed?

Experimental investigation on the complex chemical reactions between clay minerals and brine in low salinity water-flooding. Journal of Industrial and Engineering Chemistry. DOI : This paper presents a dynamic effect of clay types and content on low salinity water-flooding LSF basedon coreflooding experiments.

Enzymes And The Effect Of Ph On The Speed Of Reaction

The EDL electrical double layer expansion, MIE multicomponent ionexchangelocal pH increase between clay minerals and brine are investigated to get a betterunderstanding on the complexity of role of clay in LSF. The results of coreflooding experiments usingunconsolidated core sample show that the incremental oil recovery of kaolinite is higher than that of illiteat the same clay content. The incremental oil recovery was proportional to the local pH increase in both core samples.

Therefore, the wettability isfurther changed to the water-wet condition in kaolinite sample. The results of Ihvestigating coefficientanalysis show the kaolinite content has a strong correlation with MIE, EDL expansion, local pH increase,and oil recovery. On the other hand, the correlations between oil recovery and chemical reactions in illitesamples are relatively low compared to the kaolinite samples excepting local pH increase.

Therefore, thesandstone reservoir containing kaolinite is more suitable for the LSF. Contact us for more information.]
