1. Determine the order of the reaction A --> 2B + C from the following data obtained for [A] as a function of time. time | [A] | 0 min | 0.80 M | 8 mins | 0.60 M | 24 mins | 0.35 M | 40 mins | 0.20 M | ------------------------------------------------- Use diferential and half life. 2. Balance the equation below and determine the rate expression using the given data. Find k with units. N2 + H2 ---> NH3 (all gaseous) [N2] (mole/L) | [H2] (mole/L) | Initial Rate (mole/L /min)

sheep and follow the lead of the blind. Doris Lessing was a renowned fictional novelist of the 20th century (Lessing 652) and lived during an exciting time when questions of the normal aspects of human life were beginning to be understood. Lessing’s article "Group Minds" presents an argument that we know how people interact in groups‚ ignorance of how groups are governed is dangerous‚ and we can make changes to help the future generations. Lessing asserts her thesis that humans are social animals (652)

Psych 102 Reaction Paper #1 Raven Smith Northern Illinois University The first article “Even Geniuses Work Hard” was generally about the two different ways in how people observe intelligence and learning‚ fixed and growth mindset. Students with a fixed mindset do not like work. They believe that if you have the skill then everything should come logically. Students with a growth mindset are more likely to respond to original problems by continuing to be involved‚ trying new tactics‚ and using

SN1 Reactions For SN1 reactions it’s important to have a good leaving group because this reaction occurs in two steps. Because alcohol is such a poor leaving group it needs to be helped by silver nitrate to help promote the ionization of the alkyl halide. This helps form the products of the SN1 reaction. 2-chlorobutane This reaction didn’t occur because the carbocation isn’t stable enough for an SN1 reaction. 2-bromobutane This reaction occurred in 32 seconds. This reaction occurred quickly

No.06 Determining water potential of potato tuber cells: the weighing method If a plant cell is in equilibrium with an external solution of such a concentration that there is not net loss or gain of water‚ the water potential of the external solution will be equal to the water potential of the cell. Use of this fact can be made in estimating the water potential of a plant tissue. Samples of tissue are immersed in a range of external solutions of different strengths. The solution that induces

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

Reaction Paper The article “The Failure of the Euro: The Little Currency That Couldn ’t”‚ by Martin Feldstein‚ is a case about why the Eurozone has failed‚ is failing‚ or at best will fail. To prove his point‚ the author uses explicit examples such as the economic disaster occurring in Greece‚ while at the same time aiding the economic growth in Germany. Feldstein also demonstrates how the Eurozone also has allowed much room for error and has forced the hand of many European countries in one way

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

Reaction Paper #2 Mediactive‚ Chapters 1‚ 2‚ & 3 In today’s media world‚ we have the ability to access innumerable amounts of information. Such accessibility provides a positive impact on our lives‚ but at the same time leaves us vulnerable in conforming to information that is not trustworthy and false. We must not be passive when we are subjected to the various types of media‚ we must be active. Meaning we must analyze the information at hand and use our reason to come to a conclusion as to

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly
