DAT Destroyer Gen Chem # 77
Which of the following will lower the activation energy ?
a) using a catalyst
b) lowering the temperature
c) raising the temperature
d) increasing the pressure
e) increasing the volume
answer (a)
------------------------------------
I thought the answer can be (a) and (c) by the arrhenius equstion.
Ea=-RT ln (k/A)
However, wikipedia said the term T is cancelled by temperature decepdence 'k'.

It's bit hard to understand this part.
Anybody has this problem ?
