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.
