Question

The reaction system CS2(g) + 4H2(g) CH4(g) + 2H2S(g) is at equilibrium. Which of the following statements describes the behavior of the system if the partial pressure of carbon disulfide is reduced? As equilibrium is reestablished, the partial pressure of carbon disulfide increases As equilibrium is reestablished, the partial pressure cf hydrogen decreases As equilibrium is reestaonshed, the parttial pressure of methane, CH4, increases. As equilibrium is reestaonshed, the parttial pressure of hydrogen and hydrogen sulfide decrease. As equilibrium is reestaonshed, all the partial pressures will increase. In which of these gas-phase equilibria is the yield of products increased by increasing the total presure or the reaction mixture?

Explanation / Answer

3. For the given reaction,

At equilibrium if partial pressure of CS2 is reduced,

true statement

The equilibrium is reestablished and partial presssure of CS2 is increased

First statement is correct. This is according to the LeChatellier's principle
