Step-by-step explanation:

due to temp. increase, the half life chem. will decrease, if nuclear, there is no difference, will remain unchanged...

Step-by-step explanation:

Equation for half-life of a first order reaction is as follows.


t_(1/2) = (0.693)/(k)

where, k = rate constant

Hence, it shows that there is no relation between temperature and half-life of a reaction.

Also, in second or third order reaction there is no relation between temperature and half life. As half-life is independent of temperature.

Thus, any increase or decrease in temperature is not going to affect the half-life time of a chemical.
