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)

The mass media Newspapers‚ radio‚ television‚ and the Internet—including e-mail and blogs—are usually less influential than the social environment‚ but they are still significant‚ especially in affirming attitudes and opinions that are already established. The news media focus the public’s attention on certain personalities and issues‚ leading many people to form opinions about them.

determine the reaction time of the test participant and using the subtractive method identify the selection time and identification time of the participant. The experiments had one participant who participated in a total of 6 experiments; two experiments required a simple reaction with a single stimulus and 4 experiments that required a more complicated reaction.

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

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
