Question
3.21. A small reaction bomb fitted with a sensitive pressure-measuring device
is flushed out and then filled with pure reactant A at 1-atm 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 in Table P3.21 are 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. Find a rate
equation in units of moles, liters, and minutes which will satisfactorily fit
the data.
