Answer:
The reaction between sulfur dioxide and oxygen is reversible.
2SO2(g) + O2(g) = 2SO3(g)
Kc=280mol^-1 dm^3 at 1000K
In an equilibrium mixture at 1000K the sulfur trioxide concentration is 6.00 mol dm^-3.
What is the sulfur dioxide concentration?
A) 0.175 mol dm^-3
B) 0.254 mol dm^-3
C) 0.318 mol dm^-3
D) 0.636 mol dm^-3
