CHM220H1 Lecture 3: CHM220 Lecture 3- Irreversible vs reversible paths

Initially, only H2S is present at a pressure of0.195 atm in a closed container. What is the total pressure in thecontainer at equilibrium?

At a certain temperature, the Kp for the decomposition of H2S is 0.871. H2S(g) <------> H2(g) + S(g) Initially, only H2S is present at a pressure of 0.273 atm in a closed container. What is the total pressure in the container at equilibrium?
