Exploring the Universe Through Equations.

Advanced Chemical Half-Life Calculator

Determine the time required for a reactant to decrease by half and track its decay over time.

t1/2=0.693kt_{1/2} = \frac{0.693}{k}
t=ln⁡(A0/At)kt = \frac{\ln{(A_0 / A_t)}}{k}
Remaining Fraction=AtA0\text{Remaining Fraction} = \frac{A_t}{A_0}
Number of Half-Lives=ln⁡(A0/At)ln⁡(2)\text{Number of Half-Lives} = \frac{\ln(A_0 / A_t)}{\ln(2)}
