In a study of the gas phase decomposition of sulfuryl chloride at 600 K SO₂Cl₂(g) →SO₂(g) + Cl₂(g) the concentration of SO₂Cl₂ was followed as a function of time. It was found that a graph of In[SO₂Cl₂] versus time in minutes gave a straight line with a slope of -4.14x10-³ min-¹ and a y-intercept of -6.41. Based on this plot, the reaction is min-¹. -1 order in SO₂Cl2 and the rate constant for the reaction is

Consider the following set of reactions and the related kinetics data. The reaction conditions and initial reactant concentrations were the same for all three reactions. Select the one statement that is FALSE.  Reaction  Rate Law  Rate constant, k  (M-1s-1)   CH3F + SCN¯ → CH3SCN + F¯  Rate = k [CH3F] [SCN¯]  k = 8.3 x 10-14  CH3Cl + SCN¯ → CH3SCN + Cl¯  Rate = k [CH3Cl] [SCN¯]  k = 2.5 x 10-4    CH3I + SCN¯ → CH3SCN + I¯  Rate = k [CH3I] [SCN¯]  k = 1.5 x 10-2  OPTIONS: A) Increasing the temperature by 20ºC will increase all three reaction rates by the exact same amount. B) Doubling the concentration of SCN¯ will double the reaction rate.  C) It is possible that each reaction occurs in one elementary step. D) Each of these reactions is second order overall and first order with respect to SCN¯.  E) The reaction with CH3I as the reactant will produce CH3SCN the fastest initially.
