Answer to Question #269617 in General Chemistry for John

Question

The reaction of carbon disulfide with chlorine is as follows: CS2 (g) + 3 Cl2 (g) ⇋ CCl4 (g) + S2Cl2 (g) H = -238 kJ Predict the effect of the following changes to the system on the direction of equilibrium. a. The pressure on the system is doubled by halving the volume. b. CCl4 is removed as it is generated. c. Heat is added to the system.

Answer 1

a) when pressure is increased, the equilibrium of reaction will move to the right where products are formed. This is because the sum of all reactant moles is 4moles and occupy a larger volume than total products (2moles)

b) when carbon tetrachloride is removed, the concentration of products side will reduce. This will move the equilibrium to the right to form more carbon tetrachloride
