Using the small $x$ approximation to solve equilibrium problems

A chemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature:

$2C{H}_4(g)C_2{H}_2(g)+3H_2(g),K_p=8.{10}^{-6}$

He fills a reaction vessel at this temperature with $12.$ atm of methitne gas. Use this data to answer the questions in the table below.

Can you predict the equilibrium pressure of $C_2{H}_2,$ using only the tools available to you within ALEKS?

If you said yes, then enter the equilibrium pressure of $C_2{H}_2$ at right. Round your answer to $1$ significant digit.

yes

no atm
