Half-life and k are inversely proportional
WebJan 30, 2024 · Equation 11 is a constant, meaning the half-life of radioactive decay is constant. Half-life and the radioactive decay rate constant λ are inversely proportional which means the shorter the half … WebZero-Order Reactions. As for other reaction orders, an equation for zero-order half-life may be derived from the integrated rate law: As for all reaction orders, the half-life for a zero-order reaction is inversely proportional to its rate constant. However, the half-life of a zero-order reaction increases as the initial concentration increases.
