An equilibrium mixture of so2, o2, and so3 gases at 1500k is determined to consist of 0.344 mol/l so2, 0.172 mol/l o2, and 0.56 mol/l so3. what is the equilibrium constant for the system at this temperature? the balanced equation for this reaction is 2so2(g o2(g « so3(g.

15.41.

Explanation:

2SO₂(g) + O₂(g) ⇄ 2SO₃(g).

The equilibrium constant = Keq = [SO₃]²/[SO₂]²[O₂].

∴ Keq = [SO₃]²/[SO₂]²[O₂] = (0.56 mol/L)²/(0.344 mol/L)²(0.172 mol/L) = 15.41.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
