So what would I write for the answer? Just "increasing temperature increases reaction rate" ?

anonymous · Answer

hotter = faster. 
I mean that's the basic concept. I don't know how much you need to write to get that point across...

yes

Solubility increases with increasing temperature. So yes the rate would be faster, so this explains in general that increased temperature leads to increased reaction rate.
