Consider the following equilibrium reaction:

$C_2{H}_2(g)+2H_2(g)C_2{H}_6(g)$

The reaction begins when $C_2{H}_6$ is added to a $2\mathrm{.}00L$ flask at a constant temperature. After some time, the reaction reaches equilibrium. At equilibrium, the partial pressures are found to be:

$P_{C2H6}=5\mathrm{.}82$atm

$P_{C2H2}=1\mathrm{.}04$atm

$P_{H2}=2\mathrm{.}08$atm

Calculate the value of $K_p$ for the reaction at this temperature. Enter your answer with no units.
