A chemist is studying the following equilibrium, which has the given equilibrium constant at a certain temperature:
2CH4(g) ⇌ 3 H2(g) + C2H2(g) Kp = 7. x 10^-9
He fills a reaction vessel at this temperature with 9.0 atm of methane gas. Use this data to answer the questions in the table below.
Can you predict the equilibrium pressure of H2, using only the tools available to you within ALEKS?
If you said yes, then enter the equilibrium pressure of H2 at right.
Round your answer to 1 significant digit.
