What effect does temperature have on half-life if any?

[Spencer T]

Temperature does have an effect on half-life. As temperature increases, the rate constant increases. As the rate constant increases, the half-life decreases due to the relationship between half-life and the rate constant.

it depends how temperature affects the rate constant, if the temperature change increasese the rate constant the half life will be reduced and vice versa.

Temperature can speed up chemical reactions, making substances break down faster and reducing their half-life.

[Valeria Perez 3J]

Temperature will have an effect on the value of k, the rate constant, so it does have an impact on the half life. If your temperature increases, you should ex[ect to see an exponential increase in k due to the lowered negative exponent on the e term in the Arrhenius equation, while if the temperature goes down, the k value will also decrease due to the increase in the negative exponent. If the k value increases, your half life time will decrease, while if your k value decreases, your half life time will increase.

The kinetics of the reaction and the rate constant's temperature dependence determine how different temperatures affect a reaction's half-life. Higher temperatures typically result in a shorter half-life for reactions whose rate constants are temperature-dependent, but across a specific temperature range, the half-life of reactions whose rate constants are temperature-independent may stay essentially the same.
