Combined gas law is
PV/T = K (constant)
P = Pressure
V = Volume
T = Temperature in Kelvin
For two situations, the combined gas law can be applied as,
P₁V₁ / T₁ = P₂V₂ / T₂
P₁ = 3.00 atm P₂ = standard pressure = 1 atm
V₁ = 720.0 mL T₂ = standard temperature = 273 K
T₁ = (273 + 20) K = 293 K
By substituting,
3.00 atm x 720.0 mL / 293 K = 1 atm x V₂ / 273 K
V₂ = 2012.6 mL
hence the volume of gas at stp is 2012.6 mL
Where are the answer choices?
Kc = [b]*[c]/([a]^2) = (0.2 M)^2/(0.2 M)^2 = 1.0
To achieve equilibrium, Kc must be equal to 0.2, therefore Kc must decrease, so the concentrations of b and c must decrease and the concentration of a must increase, meaning the reaction will proceed toward the formation of a.
