Question

2SO3=2SO2+O2. If Kc=100,α=1,half of the reaction is completed, the concentration of SO3 and SO2 are equal, the concentration of O2 is​

Answer 1

Explanation:

The data is insufficient to solve this questions since conc is not given in the question

Answer 2

Concentarion of O2 is 0.01 mols/L

• Kc = ([SO3]^2) / ([SO2]^2 X [O2]) = 100
• [SO3] = [SO2]
• Kc = 1 / [O2] = 100
• [O2] = 1/100 = .01 M
• There are a lot of values not given so we make assumptions as; volume=1 L, concentration term is in mols/liter. So this result will change if the values are given different.
• Taking volume as V liters and n total number of O2 mols.
• Kc = 1 / (n/V) = 100
• n =  V/100
