The first order liquid phase reaction A $\rightarrow$ P is conducted isothermally in a plug flow reactor of 5 liter volume. The inlet volumetric flow rate is 1 liter/min and the inlet concentration of A is 2 mole/liter.
If the exit concentration of A is 0.5 mole/liter, then the rate constant, in  min$^{-1}$, is
