    What does Kp depend on...is it only tempertaure ..or is the Kp also affected by pressure and concentration of teh reactants ???

    Kp is the pressure constant, so how can it be affected by the pressure if its a constant wrt to pressure?

    Only affected by temp.

    all K's only affected by temp only.

    but wat if the reaction shifts twords the right due to an increase in temperature then woudn't the concentration of products increase and thus the value of Kp increase as well

    No, not at all. Why would it? Think about it. An increase in temperature would only increase the volume...doesn't affect the concentration at all. Concentration is the no. of moles per litre. The no. of moles does not increase or decrease if you raise the temperature.

    in fact a change in volume MUST change the concentration if the number of moles remains the same...

    but in any case kp is unaffected by changes in pressure but it IS affected by changes in temperature depending on whether the forward reaction is endothermic of exothermic.
