affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using a chromogenic

Introduction The purpose of this experiment is to determine the rate equation for the “Iodine Clock Reaction” experiment. The experiment will consider the equations 〖2I〗^-+S_2 O_8→2〖〖SO〗_4〗^(2-)+I_2 and I_2+2〖S_2 O_3〗^(2-)→2I^-+S_4 O_6 in order to determine the rate law of Rate=k[〖〖S_2 O_8〗^(2-)]〗^a 〖[I^-]〗^b by using the experimental data to calculate the values of exponents a and b as well as the rate constant k. Experimental Supplies Needed: 250 mL Erlenmeyer flask‚ 100 mL beaker‚ graduated

observe how the change in solvent polarity affects the rate and to determine the kinetics of a solvolysis reaction. In this experiment‚ we used 1-chloro-1-phenylethane in acetone in one reaction with 50% ethanol-50% water and in another reaction with 40% ethanol-60% water. To monitor he rate of reaction‚ we would need the concentration of the alkyl chloride at the beginning of the reaction and at a time t‚ but since we did not determine the concentrations‚ we monitored the rate of formation of

Laina Gray AP English 11/19/13 Doubles Tale of Two Cities describes contrasting situations dealing with London and Paris using a technique known as “doubling”. Dickens not only contrasts two ideas but also compares them to one another. This technique gives visual aid on whether something in the story is good or not so good. Contrasting London and Paris‚ the resemblance between Carton and Darnay‚ and the way that two opposite things can also be

A. Introduction Title: The effect of reading Shakespeare on reaction time Research Question: Does reading a passage of Shakespeare decrease a person’s reaction time while completing a puzzle? One day in class‚ I was reading an interesting article about how people who read and are exposed to Shakespeare and Wordsworth and other renowned writers have better brain activity‚ attention spans‚ and can have more moments of beneficial self-reflection. In the article‚ scientists and psychologists at Liverpool

Product placement‚ or embedded marketing‚ is a form of advertisement‚ where branded goods or services are placed in a context usually devoid of ads‚ such as movies‚ the story line of television shows‚ or news programs. The product placement is often not disclosed at the time that the good or service is featured. Product placement became common in the 1980s. In April 2006‚ Broadcasting & Cable reported‚ "Two thirds of advertisers employ ’branded entertainment’—product placement—with the vast majority
