Reaction KineticsLive

rate laws · Arrhenius temperature

Controls

Presets

Watch reactant concentration fall over time. The reaction order sets the curve shape; raising temperature speeds the rate constant, Arrhenius-style.

Order1

Effective k0.300

Arrheniusk = A·e^(−Ea/RT)

Governing equation

rate = k_{eff} [A]^{1} = 0.30 [A]^{1}

Reading this result: First-order: [A] decays exponentially with a constant half-life; raising temperature lifts k_eff to 0.30, steepening the curve Arrhenius-style.

Chemical Equilibrium (Le Chatelier)Live

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.

Acid–Base TitrationLive

pH curve · equivalence point

Controls

Add base to an acid and track the pH. The steep jump marks the equivalence point, where moles of acid equal moles of base.

Equivalence50.0 mL

Typestrong acid + strong base

pH at eq.7.0

Governing equation

C_{a} V_{a} = C_{b} V_{b} \Rightarrow V_{e q} = \frac{0.1 \times 50}{0.1} = 50.0 mL

Reading this result: Equivalence sits near 50.0 mL; because this is a strong acid with a strong base, the pH there is exactly 7 and the jump is nearly vertical.
