A ⇌ B shifting with stress

A (reactant)0.67 M

B (product)1.33 M

Controls

A reversible reaction A ⇌ B settles where forward and reverse rates balance. Add reactant or raise temperature and watch the equilibrium shift to relieve the stress.

Governing equation

K_{e q} = \frac{[ B ]}{[ A ]} = \frac{1.33}{0.67} \approx 2.00

Reading this result: Effective K is near 1, so A and B coexist in comparable amounts and a small stress can tip the balance either way.

Governing equation

P V = n R T : 103.9 kPa \times 24 L = 1 mol \times 8.314 \times 300 K

Reading this result: At 300 K, 1 mol in 24 L, PV = nRT gives about 103.9 kPa (1.03 atm). Mean molecular speed scales with the square root of temperature, so this gas moves about 1.00x as fast as it would at 300 K. Around room temperature the molecules carry moderate kinetic energy. Expanding the volume spreads the molecules out, lowering the collision rate and the pressure.
