At a certain temperature, the Kp for the decomposition of H2S is 0.814 atm. EASY 10 PTS?
Initially, only H2S is present at a pressure of 0.271 atm in a closed container. What is the total pressure in the container at equilibrium?
I am having trouble setting up the first part
I set it up as 0.814=(x)(x)/0.271-x and I know I have to rearrange to solve it as a quadratic, but how do I get c for the formula?
