What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well

The plasma membrane is a fluid phospholipid bilayer. The outside of the bilayer is hydrophilic portions of porteins and phospholipids because they are exposed to water. This results in a stable membrane structure. Inside the bilayer hydrophobic portions of proteins and phospholipids because the inside of the bilayer is nonaqueous. the proteins bob in the fluid bilayer of phospholipids. The proteins also vary in structure and function. There are teh integral proteins; transmembrane

Discuss the effects of increased concentration in transport markets. Concentration ratio refers to the market share of the largest firms in an industry. For example‚ a 5 firm concentration ratio of 65% means that the 5 largest firms have more 65% of market sales. If the concentration ratio increased‚ then 1 or 2 firms may start to dominate the market and the firms will be able to exercise Monopoly power. (in UK legal definition of a monopoly is a firm with more than 25%) This is likely to cause many

Assignment Question: Comparison of Mass society theory with limited effect paradigm. Submitted to: Sir Zeeshan Zaigum Submitted by: Sana Nasir Powerful Effect Paradigm: In powerful effect paradigm‚ media has immediate‚ direct influence and assumes that people are passive and absorb media content uncritically & unconditionally. That paradigm related to Frankfurt school of though. Three theories come under this paradigm; one is Mass society theory‚ second is Magic bullet theory and

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values‚ subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 | | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 | | 0

This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function

BAD EFFECTS OF CELL PHONE ON SOCIETY A report by the International Telecommunication Union (ITU) said there were about six billion cell phone subscriptions at the end of 2011-roughly one for 86 of every 100 people. Up to now‚ this number has continued to increase dramatically. This proves certainly that cell phone affects our society more strongly and more deeply in many aspects. No one can deny that cell phone is playing a very important and necessary role in our society because it not only
