Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this

Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride.

A precipitate is solid that is formed from a chemical reaction. A cation is a positively charged ion and an anion is a negatively charged ion. Hypothesis: The anion and the cation will react to form a precipitate more often than not.

But do people really realize the differences between conventional and organic products as they mound their shopping carts? Do they know that the main differences between the two categories of foods actually lie in their processing procedures‚ advertising strategies‚ and product ingredients? When people look at an organic product‚ the first thing they are most likely to notice

by Georg Wittig in 1954‚ the Wittig reaction is a robust organic synthesis method for preparing stereospecific alkenes. In general‚ Wittig reactions involve an aldehyde or ketone and a Wittig reagent (triphenylphosphonium ylide) and result in the formation of an alkene product and triphenylphosphine oxide (side product). Stereospecific alkene products can be synthesized by adjusting the reaction reagents and conditions. In the 60 years since the Wittig reaction was discovered‚ many articles have
