A zero-order gas phase reaction A→B with rate (-rA)=k=100 mol/(L min) is carried out in a mixed flow reactor of volume 1 L. Pure A is fed to the reactor at a rate of 1 mol/min. At time t=0 the outlet flow is stopped while the inlet flow rate and reactor temperature remain unchanged. Assume that the reactor was operating under steady state before the flow was stopped (t<0). The rate of consumption of A, -dCA/dt, in mol/(L min), at t=1 min is
A
63.2
B
36.8
C
90.6
D
99.0

Correct : d
