The system described by the reaction CO(g)+Cl2(g)⇌COCl2(g) is at equilibrium at a given temperature when PCO= 0.26 atm , PCl2= 0

givi [52]

<u>Answer:</u> The new pressure of CO is 0.09 atm

<u>Explanation:</u>

For the given chemical reaction:

$CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)$

The expression of $K_p$ for above equation follows:

$K_p=\frac{p_{COCl_2}}{p_{CO}\times p_{Cl_2}}$ .......(1)

We are given:

$p_{COCl_2}=0.66atm\\p_{CO}=0.26atm\\p_{Cl_2}=0.15atm$

Putting values in above equation, we get:

$K_p=\frac{0.66}{0.15\times 0.26}\\\\K_p=16.92$

Addition pressure of chlorine added = 0.39 atm

Now, the equilibrium is re-established:

$CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)$

Initial: 0.26 0.15 0.66

At eqllm: 0.26-x 0.54 0.66+x

Putting values in expression 1, we get:

$16.92=\frac{(0.66+x)}{(0.26-x)\times 0.54}\\\\x=0.17$

So, new pressure of CO = 0.26 - x = (0.26 - 0.17) = 0.09 atm

Hence, the new pressure of CO is 0.09 atm
