Phosgene, $C O C l_{2}$ , a poisonous gas decomposes according to the equation

$C O C l_{2} (g) ⇌ C O (g) + C l_{2} (g)$

If $K_{c} = 0.083$ at $900 ° C$ , what is the value of $K_{c} ?$

Options:

Answer:

Solution:

$K_{p} = K_{c} {(R T)}^{Δ n_{g}}$

where $Δ n_{g} = (1 + 1) - 1 = 1, R, = 0.082 L atm mo l^{- 1} K^{- 1}$ and $T = 1173$ K

So $K_{p} = K_{c} (R T)^{1} = 0.083 \times 0.082 \times 1173$

$7.98 ≃ 8.0$
