and chemists all over the world. What happenes during a reaction is atoms or molecules that collide and form new molecules. You can affect this rate of reaction with: temperature of reactants or suroundings‚ surface area of reactants‚ if there is a catalyst present‚ but in theis lab the concentration was changed as the IV. The reaction rate is masured in change/time‚ in this case it was: volume of gass produced/minutes. Gas was measured in ml/minute‚ and this was the DV. Aim of lab was: To find the

reaction was hindered. Greatest color change‚ hence greatest enzyme activity is seen at a neutral pH of 7.0‚ concerning the buffer solution. Increase and decrease in pH within the buffer seems to put strain on the enzyme¡¦s ability to act as a catalyst and hence decreased the rate and completeness of the reaction. Graph Three

Into the world is a concept that represents journey‚ change‚ and going from the old world into a new world. To go from old to new‚ one must first experience a disruption or a catalyst‚ and go through a process of obstacles such as parents‚ culture and the society in order to adjust and fit in the new world. This adjustment can have either positive or negative consequence on the self and others around. The film bend it like Beckham (BILB) effectively explores this concept as the audience can easily

waited for that‚ there would be no way for the organism to obtain energy or in turn survive. This is where biological catalyst comes into play. (Ophardt‚ 2003) In the year of 1836‚ Jacob Berzelius‚ introduced the concept of a catalyst (enzyme). By studying the effects of acids and bases in the decomposition of hydrogen peroxide he developed the notion of biochemical catalysts. There were many conflicting thoughts on this‚ and it wasn’t until Edward Buchner experimented on this topic in 1897 that

Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

POLLUTION FROM DIESEL ENGINES AND ITS CONTROL Diesel engines and gasoline engines are the most widely used primary sources of power in automobiles and the sheer number of them makes the issue of emissions from these engines an important one. Table 1 gives a comparison of the amounts of different pollutants in the exhaust of diesel and petrol engines. FORMATION OF NOX AND CONTROL METHODS: The main source of NOx in diesel engine emissions is the oxidation of the nitrogen in the air at the high temperatures
