Two isomers (A and B) of a given compound dimerize as follows: 2Ak1A22Bk2B2 Both processes are known to be second order in reactant, and k1 is known to be 0.250 L/mol s at 25C. In a particular experiment A and B were placed in separate containers at 25C, where [A]0 = 1.00 102M and [B]0 = 2.50 102 M. It was found that after each reaction had progressed for 3.00 min, [A] = 3.00[B]. In this case the rate laws are defined as Rate=[A]t=k1[A]2Rate=[B]t=k2[B]2 a. Calculate the concentration of A2 after 3.00 min. b. Calculate the value of k2 . c. Calculate the half-life for the experiment involving A.
The acid-catalyzed iodination of acetone CH3COCH3(aq) + I2(aq) CH3COCH2I(aq) + HI(aq) is a common laboratory experiment used in general chemistry courses to teach the method of initial rates. The reaction is followed spectrophotometrically by the disappearance of the color of iodine in the solution. The following data (J. P. Birk and D. L Walters, Journal of Chemical Education, Vol. 69, p. 585, 1992) were collected at 23 C for this reaction. Determine the rate law for this reaction.
The thermal decomposition of diacetylene, C4H2, was studied at 950 C. Use the following data (K. C. Hou and H. B. Palmer, Journal of Physical Chemistry. Vol. 60, p. 858, 1965) to determine the order of the reaction.
