102. Solving a chemistry problem

1. Using the reaction rate constants k1 and k2 at two temperatures T1 and T2, respectively (see Table), calculate the activation energy of the reaction.
2. At the larger of the two given temperatures, determine the half-life τ1/2 and the decrease in the concentration x of the reagent (reagents if their initial concentrations C0 are the same and they interact with equal stoichiometric coefficients) by the time τ.
3. Determine by analytical method the reaction rate constant at temperature Tx and plot the dependence lnk=f(103/T).
4. Determine the temperature coefficient of the reaction rate.
Instruction. The values ​​of temperatures T1 and T2 are taken in the order they are indicated in Table. to Problem 2.1, regardless of their values.
