Question

A vessel at 1000 K contains CO 2 ​ with a pressure of 0.5 atm . Some of the CO 2 ​ is converted into CO on the addition of graphite. If the total pressure at equilibrium is 0.8 atm , the value of K is

TestHub · Accepted Answer

Total pressure at equilibrium = 0.8 atm ; Total no.of moles = p + x . Therefore p ∝ n ; 0.8 0.5 ​ = p + x p ​ ⇒ x = 0.3 K p ​ = P CO 2 ​ ​ P CO 2 ​ ​ = 0.2 0.6 × 0.6 ​ = 1.8 atm
