CS2(g) + 3 Cl2(g) → CCl4(g) + S2Cl2(g)
Carbon tetrachloride , CCl4(g), can be synthesized according to the reaction represented above. A chemist runs the reaction at a constant temperature of 120°C in a rigid 25.0 L container.
Chlorine gas, Cl2(g), is initially present in the container at a pressure of 0.40 atm.
At 30°C the reaction is thermodynamically favorable, but no reaction is observed to However, at 120°C, the reaction occurs at an observable rate.
S2Cl2 is a product of the reaction .
CCl4(g) can also be produced by reacting CHCl3(g) with Cl2(g) at 400°C , as represented by the equation below.
CHCl3(g) + Cl2(g) → CCl4(g) + HCl(g)
At the completion of the reaction a chemist successfully separates the CCl4(g) from the HCl(g) by cooling the mixture to 70°C, at which temperature the CCl4(g) condenses while the HCl(g) remains in the gaseous state.
