Answer:
5.79
Explanation:
The following data were obtained from the question:
Concentration of SO2, [SO2] = 1.50 M
Concentration of O2, [O2] = 0.120 M
Concentration of SO3, [SO3] = 1.25 M
Equilibrium constant, (K) =..?
The balanced equation for the reaction is given below:
2SO2(g) + O2(g) <==> 2SO3(g)
From the balanced equation, the equilibrium constant K is written as follow:
K = [SO3]²/ [SO2]²• [O2]
With the above, the value of the equilibrium constant, K can be obtained as follow
K = [SO3]²/ [SO2]²• [O2]
K = (1.25)² / (1.50)² × 0.120
K = 1.5625 / ( 2.25 x 0.120)
K = 5.79
Therefore, the equilibrium constant is 5.79.
