What additional information would be needed to calculate the rate in units of concentration per time?
This must refer to some other question.
A flask is charged with 0.100 mol of A and allowed to react to form B according to the hypothetical gas-phase reaction A(g)--> B(g) The following data are collected:
Time (s) 0 40 80 120 160
Moles of A .100 .067 .045 .030 .020
Wouldn't that be the volume? You have moles but no volume. For M you need moles/L.
