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.
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 What happens to a reaction rate as temperature drops? Give two explanations for the change. State which one is more important and explain why. b How does a catalyst affect reaction rates? c Compare reaction rates when a given reactant concentration is high with the rate when the concentration is low. Explain the difference.
For the gas-phase reaction 2H2+O22H2O rxnG is 457.18kJ. What does a graph of G versus lnQ lnQ varying from 50 to +50 look like at 25C? Change the temperature and find out if the graph looks substantially different at different temperatures.
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.
For the following two reactions H+Cl2HCl+Cl H+Br2HBr+Br the first reaction has a lower value of A than the second reaction. What can one say about the relative properties of the intermediates HCl2 and HBr2, just from the relative values of A?
Old-fashioned smelling salts consist of ammonium carbonate, (NH4)2CO3. The reaction for the decomposition of ammonium carbonate (NH4)2CO3(s)2NH3(g)+CO(g)+H2O(g) is endothermic. Would the smell of ammonia increase or decrease as the temperature is increased?
By which of the following mechanisms does a catalyst operate? a. It decreases the activation energy barrier for a reaction. b. It serves as a reactant and is consumed. c. It increases the temperature of a reaction. d. It increases the concentration of reactants.
Define these terms: (a) unimolecular reaction (b) bimolecular reaction (c) elementary reaction (d) overall reaction
