$P=0.378\ atm$

Work Step by Step

Initial concentration: $0.05\ mol\div 12.5\ L=0.004\ M$, reacted concentration: x $K_c=[CO][Cl_2]/[COCl_2]$ $0.0071=x\times x/(0.004-x)$ $x^2+0.004x-2.84\times10^{-5}=0$ $x=0.00369$ Total concentation: $x+x+(0.004-x)=0.00769\ M$ Pressure: $P=CRT$ $P=0.00769\ M\times 0.082\ atm/M.K\times600\ K=0.378\ atm$
