The Haber process is typically carried out at a temperature of approximately . The rate of the forward reaction would be decreased if the temperature were lowered to
.
For every increase in temperature, most reactions double in rate. On the other hand, a temperature that is too low cannot be used because the rate of the reaction will be significantly slowed. As a result, a compromise temperature
is used, which is high enough for the rate to be quite fast but low enough to yield a relatively high ammonia yield. This reaction takes place at a pressure of 200 atm.
Higher temperatures accelerate the rate of reaction. We've seen that when reactions are carried out at a higher temperature, the rate of reaction increases. A higher temperature would allow the Haber process to occur more quickly.
Temperature increases typically increase the rate of reaction. The average kinetic energy of the reactant molecules increases as the temperature rises. As a result, a larger proportion of molecules will have the minimum energy required for an effective collision.

Answer: half life
Explanation: Radioactive decay follows first order kinetics and the time required for the decay of a radioactive material is calculated as follows:
t= time required
k= disintegration constant
x= amount of substance left after time t
a= initial amount of substance
when one half of the sample is decayed, one half of the sample remains and t can be represented as
at ,
