Carbon tetrachloride reacts at high temperatures with oxygen to produce two toxic gases, phosgene and chlorine.CCl4(g) + (1/2)O2

Elodia [21]

Answer : The value of $K'_c$ for the reaction is, $1.9\times 10^{19}$

Explanation :

The given equilibrium reactions are:

(1) $CCl_4(g)+\frac{1}{2}O_2(g)\rightleftharpoons COCl_2(g)+Cl_2(g)$ $K_c=4.4\times 10^9$

(2) $2CCl_4(g)+O_2(g)\rightleftharpoons 2COCl_2(g)+2Cl_2(g)$ $K'_c=?$

As we know that, when we are multiplying the equation (1) by 2 then we get the equation (2). Thus, the relation between the two equilibrium constant will be,

$K'_c=(K_c)^2$

So,

$K'_c=(4.4\times 10^9)^2$

$K'_c=1.9\times 10^{19}$

Therefore, the value of $K'_c$ for the reaction is, $1.9\times 10^{19}$
