Which reaction mechanism assumptions are unimportant in describing simple ionic reactions between cations and anions? Why?
In Chapter 3, we discussed the conversion of biomass into biofuels. One important area of research associated with biofuels is the identification and development of suitable catalysts to increase the rate at which fuels can be produced. Do a web search to find an article describing biofuel catalysts. Then, write one or two sentences describing the reactions being catalyzed, and identify the catalyst as homogeneous or heterogeneous.
Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a. Pure A and B are mixed, and after 12.0minutes the measured concentration of C is 0.396mol/L. b. Pure A,B, and C are mixed together at equal concentrations of 0.300M. After 8.00minutes, the concentration of C is found to be 0.455M.
A proposed mechanism for the gas-phase chlorination of methane is Cl2+CH4CH4Cl+ClCH4ClCH3+HClCH3+Cl2CH3Cl+ClCl+CH4CH3+HCl Suppose the first step is the RDS. What is the expected rate law in terms of the original reactants, Cl2 and CH4? How would you determine if this mechanism might be a potentially correct or, for that matter, a potentially incorrect one?
Azomethane decomposes into nitrogen and ethane at high temperatures according to the following equation: (CH3)2N2(g)N2(g)+C2H6(g)The rate of the reaction is followed by monitoring the disappearance of the purple color due to iodine. The following data are obtained at a certain temperature. (a) By plotting the data, show that the reaction is first-order. (b) From the graph, determine k. (c) Using k, find the time (in hours) that it takes to decrease the concentration to 0.100 M. (d) Calculate the rate of the reaction when [ (CH3)2N2 ]=0.415M.
Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a. Pure A,B, and C are mixed together at concentrations of A+B=0.400M, C=0.150M. After 6.00minutes, the concentration of C is 0.418M. b. Pure A, and B are mixed together at same concentrations of 0.361M. After 7.00minutes, the concentration of A is found to be 0.048M.
