Controls

pH measures hydrogen-ion concentration on a logarithmic scale. Each unit is a 10× change — pH 3 is ten times more acidic than pH 4.

pH3.00

[H⁺]1.0e-3

[OH⁻]1.0e-11

Governing equation

pH = - lo g_{10} [H^{+}] = - lo g_{10} (1.0 e - 3) = 3.00

Reading this result: Acidic: [H⁺] of 1.0e-3 M outnumbers OH⁻, and because pH + pOH always sums to 14, the pOH here is 11.0.

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

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.
