Question

The following reaction was monitored as a function of time: AB→A+B A plot of 1/[AB] versus time yields a straight line with slope 5.8×10−2 (M⋅s)−1 . You may want to reference (Page) section 13.4 while completing this problem.

Part A Part complete What is the value of the rate constant (k) for this reaction at this temperature? Express your answer using two significant figures. -- SubmitPrevious AnswersRequest Answer Part B Part complete Write the rate law for the reaction. -- Write the rate law for the reaction. k k = M−1s−1 SubmitPrevious AnswersRequest Answer Part C Part complete What is the half-life when the initial concentration is 0.52 M ? Express your answer using two significant figures. -- Rate=k Rate=k[AB] Rate=k[AB]2 Rate=k[AB]3 SubmitPrevious AnswersRequest Answer Part D Part complete If the initial concentration of AB is 0.230 M , and the reaction mixture initially contains no products, what are the concentrations of A and B after 80 s ? Express your answers numerically using two significant figures, separated by a comma. -- t1/2 t 1 / 2 = nothing s [A],[B] [ A ] , [ B ] = M
