Ace chemistry student Sidney Einstein (no relation) was carrying out a kinetics experiment in lab which produces iodine and uses starch as an indicator. In the first minute after mixing, Sidney spilled some of the solution. Rather than start over, he decided to pour out more solution until he had exactly half the original volume in the tube. Given that the particular reaction under investigation was second order in the reactant being investigated and was supposed to change color after 10 minutes, approximately how long (minutes) will it be before Sidney sees a color change? Explain briefly!
In a kinetic study of the reaction \(2 \mathrm{~A}(g)+\mathrm{B}(g) \rightarrow \mathrm{P}(g)\) the following rate data were obtained. Write the rate law with proper orders. Give the overall order of the reaction. Finally, state what this problem confirms about the relationship between reactant orders and coefficients in the balanced equation. $$\begin{array}{cccc} & & & \begin{array}{l} \text { Rate of } \\ \text { disappearance } \end{array} \\ \text { Experiment } & {[\mathbf{A}]} & {[\mathrm{B}]} & \text { of A }(\mathrm{M} / \mathrm{s}) \\ \hline 1 & 0.0125 \mathrm{M} & 0.0253 \mathrm{M} & 0.0281 \\ 2 & 0.0250 \mathrm{M} & 0.0253 \mathrm{M} & 0.0562 \\ 3 & 0.0125 \mathrm{M} & 0.0506 \mathrm{M} & 0.1124 \end{array}$$
In the substitution reaction of \(\mathrm{Cl}^{-}\) for \(\mathrm{OH}^{-}\) in 2-propanol, explain how \(\mathrm{Zn}^{2+}\) acts as a catalyst to increase the reaction rate.
Why would decreasing the volume of a container in which a gas-phase reaction is taking place speed up the reaction?
