The oxidation of sulfur dioxide by oxygen to sulfur trioxide has been implicated as an important step in the formation of acid r

Igoryamba

Answer:

The value of the equilibrium constant $K_p$ at this temperature is 3.42.

Explanation:

Partial pressure of the sulfur dioxide = $p_1=0.564 atm$

Partial pressure of the oxygen gas = $p_2=0.102 atm$

Partial pressure of the sulfur trioxide = $p_3=0.333$

$2 SO_2(g) + O_2(g)\rightleftharpoons 2 SO_3(g)$

The expression of an equilibrium constant is given by :

$K_p=\frac{(p_3)^2}{(p_1)^2\times p_2}$

$K_p=\frac{(0.333 atm)^2}{(0.564 atm)\times (0.102 atm)}=3.42$

The value of the equilibrium constant $K_p$ at this temperature is 3.42.
