Question

what is the effect of temperature on activation energy?

Answer 1

activation energy increases

Answer 2

$\rightarrow\huge\text{Answer}$

☛As temperature increases, molecules gain energy and move faster and faster. Therefore, the greater the temperature, the higher the probability that molecules will be moving with the necessary activation energy for a reaction to occur upon collision.

☛It is said that activation energy does not change with temperature. ... If we increase the temperature, the kinetic energy of the molecules will increase and they will need less extra energy and hence lesser activation energy to overcome the threshold energy barrier.
