Temperature (K)

Reactions speed up with temperature because more molecules clear the activation-energy barrier. The Arrhenius law k = A·exp(−Ea/RT) captures this — plotting ln k against 1/T gives a straight line whose slope reveals Ea. Educational tool.

Rate constant k1.72e+2

k at T + 10 K3.31e+2

Speed-up per +10 K1.9×

Governing equation

k = A e^{- E_{a} / R T} = 1 0^{11} e^{- \frac{50 \times 1 0 ^{3}}{8.314 \times 298}} = 1.72 e + 2 s^{- 1}

Reading this result: At 298 K the +10 K speed-up is 1.9× — the barrier Ea sets the slope −Ea/R of the straight Arrhenius line, so higher Ea tilts it steeper and heat matters more.
