How to increase the velocity of a reaction?

I'm doing relatively simple Chemistry but I've been given a formula for the velocity of a reaction.


$$v= k \cdot c\_\mathrm A^a$$


and


$$k= A \cdot \mathrm e^{E\_\mathrm a/RT}$$


As a result, from that formula, surely decreasing the temperature $T$ would increase the velocity of the reaction? As that would increase the value of $k$ and therefore drive up the reaction speed? Also, same thinking, increasing the activation energy $E\_\mathrm a$.


I know that's wrong, because common sense. But the formula is lying to my face. 




It should be $-E\_a/RT$


Therefor, increasing the temperature, lowering the activation energy (catalysis), or increasing the concentration of reactant(s) would increase the reaction velocity.
