7 The data that follow are typical of the liquid-phase decomposition of an organometallic vanadium compound. The stoichiometry of this irreversible reaction is of the form 2A -? B + C The solution is prepared in a manner such that a weight of material corresponding to 0.75 mol of reactant A is dissolved in 1 L of solution. However, it is thought that some of this material has decomposed during storage, so that the initial concentration of species A is uncertain. Furthermore, the analytical data for the samples taken at 10 and 20 h are suspect because of a malfunction of the spectrometer employed for the analyses. Test these data to ascertain whether or not they are consistent with a rate expression that is 3/2-order in species A. Prepare an appropriate plot of the data to perform this test. If this rate expression is consistent with the data, what is the value of the rate constant?
