Problem 6-7 (Level 1) The following data were obtained for
the irreversible, gas-phase reaction
A + B \rightarrow R + S
using an isothermal, ideal plug-flow reactor. The feed contained
a stoichiometric mixture of A and B in N$_2$. The feed concen-
tration of A was 0.005 mol/l.

Are the above data consistent with the assumption that
the reaction is second order overall? Support your answer
quantitatively.
