Question:

Example 14-8 illustrated the chlorination of methane to form chloromethane:

Example 14-8 also revealed that at equilibrium, the products were strongly favored. However, the substitution of chlorine for hydrogen can continue in subsequent reactions, forming dichloromethane, chloroform, and carbon tetrachloride:

(R2): (R3): (R4): CHCl + Cl CHCl + HCl CHCl + Cl CHCl, + HCl CHCI + ClCCI + HCI 4

A steady-state reactor is maintained at P = 1 bar and T = 1000°C. Assuming the product stream leaving the reactor is at equilibrium, find its composition if the reactor feed consists of the following.

A. 1 mol/s of methane and 4 mol/s of chlorine

B. 1 mol/s of methane and 1 mol/s of chlorine

Use the shortcut method to account for the effects of temperature.
