A) decreases with increasing temperature
B) increases with increasing temperature
C) does not depend on temperature
D) depends on the height of the potential barrier
Correct Answer: A
Solution :
The rate of reactions exhibiting negative activation energy decreases with increasing temperature because the reaction with the greater activation energy will be faster at the higher temperature. and \[k=A{{e}^{-{{E}_{a}}/RT}}\] when \[{{E}_{a}}=-ve\] \[\therefore \] \[k=A{{e}^{+{{E}_{a}}/RT}}\]You need to login to perform this action.
