Reaction Rates and EFFECT of temperature...

Umm...Im looking at an EK problem and they gave a Reaction that was exothermic. The question asks what the effect of increasing the temperature will have on the forward reaction. The answer was the the forward reaction will increase.

Now, I am confused about one thing...I thought that that increasing temperature (due to le chateliers) will favor the reaction of the reverse endothermic reaction and thus shouldnt the forward reaction decrease?

My guess on this question: KINETICALLY- the temp increases both the forward and reverse reactions but in terms of Equilbrium...the concentrations of the reactants will increase and the concentrations of products will decrease; if this is the case, doesnt this suggest the reverse rate will be faster than the forward rate (even though both increase)??

I think you're correct. If it's an exothermic reaction, the equilibrium will shift to the left when the temperature is increased. But from the wording, they don't seem to be referring to the equilibrium so much as they are referring to reaction rates. The rates of both the forward and reverse reactions will increase, but the equilibrium will shift towards the reverse reaction.
