use the shortcut van ’t Hoff equation to determine the flow rate of benzene in the exiting stream.

Benzene can be formed by the dehydrogenation of cyclohexane:



If 1000 mol/s of pure cyclohexane enters a steady state reaction, and the stream leaving the reactor is a vapor phase mixture at P = 0.1 MPa and T = 500 K,

A. 0 mol/s

B. 122 mol/s

C. 1000 mol/s

D. 1366 mol/s

E. The problem cannot be solved.


B. Correct. This is the rate of benzene leaving the reactor if the shortcut van ‘t Hoff assumption is correct.
