13. Solving a chemistry problem

3. According to the reaction presented in Table 9 and using its kinetic data, calculate, according to the option:
1) The order and rate constant of the reaction.
2) Write a general expression for the true rate of the reaction according to the change in the concentration of the substance indicated in table 9.
3) According to the calculated (item 1) order of the reaction, write the kinetic equation for the reaction rate.
Assume that the second component in the reaction is taken in large excess and the reaction rate is controlled by the change in the concentration of the substance indicated in Table 9.
