# Determination of Equilibrium Concentrations of Gas Reaction

CHEM-FVPCFU

The gas-phase dissociation of phosphorus pentachloride to phosphorous trichloride and chlorine gas at $540°C$ has a $K_p$ of $3.60$.

What is the partial pressure of each of the three substances if $0.50 \textrm{ moles}$ of $\textrm{PCl}_5$ and $2.0 \textrm{ moles}$ of $\textrm{PCl}_3$ are combined and brought to equilibrium at this temperature and at a total pressure of $2.00 \textrm{ atm}$?

$\textrm{PCl}_5$:

.
$\textrm{PCl}_3$:
