Q 2(a) For a reaction A ? P, if the concentration of A was determined at different time intervals during the course of the reaction, explain what you would plot to determine if the reaction was first order or second order with respect to the reactant. Q 2(b)

Step 1
For a first order reaction, the plot of the natural logarithm (ln) of the concentration of A against time would give a straight line with a negative slope. This is because the rate of a first order reaction is directly proportional to the concentration of the Show more…

Consider the reaction A → B The rate of the reaction is 1.6 ! 10−2 M/s when the concentration of A is 0.35 M. Calculate the rate constant if the reaction is (a) first order in A, and (b) second order in A.

The reaction $$ 2 \mathrm{I}^{-}(a q)+\mathrm{S}_{2} \mathrm{O}_{8}^{2-}(a q) \longrightarrow \mathrm{I}_{2}(a q)+2 \mathrm{SO}_{4}^{2-}(a q) $$ was studied at $25^{\circ} \mathrm{C}$ . The following results were obtained where a. Determine the rate law. b. Calculate a value for the rate constant for each experiment and an average value for the rate constant.
