Two consecutive reactions occur according to the reaction scheme shown below: $\mathrm{A}\stackrel{{\mathrm{k}}_1}{⟶}\mathrm{I}\stackrel{{\mathrm{k}}_2}{⟶}\mathrm{P}$ The values for each of the rate constants are: $k_1=0.12{\mathrm{s}}^{-1}$ and $k_2=0.14{\mathrm{s}}^{-1}$. (a) Evaluate if this reaction is time dependent or time independent. Explain your reasoning. $[2$ marks $]$ (b) Evaluate the half-life for A. Show working. $[2$ marks $]$ (c) In an experiment where the initial concentration of A was $0.54\mathrm{M}$ calculate the concentration of species I after $6\mathrm{s}$. Show working. [3 marks $]$ (d) Sketch the concentration versus time profile for each of the species A, I, and P for the reaction described above where the initial concentration of $\mathrm{A}$ is $0.54\mathrm{M}$. Indicate calculated values on the $\mathrm{x}$-axis and $\mathrm{y}$-axis. [3 marks]
