34. Решение задачи по химии №003 402

9. A chemical reaction occurs in the system with an unknown integer reaction order and a single product B. The reaction can be described by the equation A=B or 2A=B, i.e. the order is either 1 or 2. There is no product B at the initial moment. Data on the concentration of reagent A at different points in time are given in the table
time, min 0 4 8 14 18 24 34 42
s, mol/m3 240 161 108 59 40 22 8 4
According to the table you need:
1. Plot the kinetic curve of the reagent
2. According to the kinetic curve:
- determine the concentration of the reagent at 10 minutes;
- determine the half-life of the reagent;
- determine which order (first or second) this reaction belongs to;
- Determine the concentration of the product at 20 minutes.
