First-Order Half-Life — food spoilage

About First-Order Half-Life — food spoilage

Calculate the first-order half-life for food spoilage from the rate constant k. t½ = ln2 / k. The calculation uses t½ = ln2 / k. The stakes: Whether a reaction is spontaneous, how fast it goes, and how its equilibrium shifts with temperature all flow from a handful of equations. Sign and unit errors here are notoriously easy to make. Half-life is constant (concentration-independent) for first-order kinetics. Watch out for: dropping the minus sign in ΔG = ΔH − TΔS; confusing rate constant with equilibrium constant; mixing J and kJ for ΔH vs ΔS. Because the calculation happens entirely client-side, you can use it offline and with confidential data, then cite the stable URL in your methods or teaching notes.
