3. A small reaction bomb (assumed to be constant volume) fitted with a sensitive pressure-measuring device is filled with pure reactant A at 1.0 atm of pressure. The operation is carried out at 25°C, a temperature low enough that the reaction does not proceed to any appreciable extent. The temperature is then raised as rapidly as possible to 100°C by plunging the bomb into boiling water, and the readings below were obtained. The stoichiometry of the reaction is 2A → B, and after leaving the bomb in the bath over the weekend the contents are analyzed for A; none can be found. t (min) 1 P (atm) 1.14 t (min) P (atm) 6 0.870 2 1.04 7 0.850 3 0.982 8 0.832 4 0.940 9 0.815 5 0.905 10 0.800 a. Determine the rate equation in units of moles, liters, and minutes which will satisfactorily fit the data. b. Plot the concentrations of A and B versus time from t=0 to 10 min.
