1. The formation of a certain substance, proceeding according to the equation A B \u003d AB, is a second-order reaction. The change in the concentration of reagents over time is shown below:
τ, min 0 12 18 24 30 42
SA=CB
mol/l 0.01873 0.01794 0.01764 0.01734 0.01704 0.01644
Calculate the rate constant and the concentration of AB 2 hours after the start of the reaction, if the volume of the system does not change.
