The conversion A → B takes place in the liquid phase. After 12 minutes from the start of the reaction, the concentration of substance A CA = 0.36 mol dm³ was detected in the reaction mixture, after 31 minutes from the start of the reaction, the concentration of substance A decreased to 0.19 mol dm³. At time 2720 s from the beginning, the concentration of starting substance A in the reaction mixture had a value of 0.14 mol dm-3. The initial concentration of substance A was 0.83 mol dm³. Based on these data, decide if the reaction is first or second order and calculate the rate constant.
