Worksheet: Rate Laws from Concentration Data


The isomerization of a gaseous compound is of the first order and has a rate constant of 2 . 6 1 × 1 0 4 s−1. Determine, to two significant figures, the concentration of the reactant after 45.0 minutes if the isomerization reaction is carried out at 1 5 0 C in a 0.300 L flask with an initial reactant partial pressure of 48.5 torr.
