ok , let me get this straight

k decreases with temp. (endothermic reaction)?

k increases with temp. (exothermic reaction) ??

For a reaction that is endothermic in the forward direction, increasing the temperature favours the forward reaction meaning products > reactant which will increase k.

Opposite for exothermic obviously.

thanks

how much do we need to know about the equilibrium constant? i know nothing about it!

the-intercepter · 5 Nov 2008, 2:56 PM

ill tell ya about 12:30 tommrow afternoon lol

I just checked coz i was always wrong and those sort of questions are always worth 3-4 marks

For endothermic equilibria, K increases with increasing temperature. For exothermic equilibria, K decreases with increasing temperature. (From the Macquarie Book)

outside the syllabus now

Yeah, its just for Industrial Chemistry option.

it is in the syllabus..= =. It is in the Macquarie Book for Industrial Chemistry.
