This question is also based on
Arrhenius equation [attachment id=0 msg=2849]
Now check qualitative relation in
Temperature and k value As T increase ,rate constant increases because of higher frequency of collisions. [attachment id=1 msg=2849]
However slope of the line is
-Ea/R means if
activation energy is high then rate constant is low and rate of the reaction is low.This Arrhenius equation is proving mathematically. But we also know that high activation energy means less molecules can cross the activation energy barrier and less rate of the reaction means less rate constant.
