Question

Equilibrium Learning Check #1Sulfuric acid is an important industrial chemical that is usually produced by a series of reactions. One of these involves and equilibrium between gaseous sulfur dioxide, oxygen and sulfur trioxide. 2SO2(g) + O2(g) ↔ 2SO3(g) If 2.5 mol of sulfur dioxide gas and 2.0 mol of oxygen gas are placed in a sealed 1.0L container and allowed to reach equilibrium, 0.75 mol of sulfur dioxide remains at equilibrium. Use an ICE table to determine the concentration of the other gases at equilibrium.

Answer 1

answer and explanation

below we show an ICE table

now that we have the mols at equilibrium we can calculate the concentration for the gases

for SO₂

concentration = 0.75mol/1L

= 0.75M

for O₂ gms

concentration = 1.125mol/1L

= 1.125M

for SO₃

concentration = 1.75mol/1L

=1.75M
