Title: Equilibrium Question
Post by: TRoi on July 13, 2009, 10:03:18 pm

Hi everyone,

I have a question (section B) on equilibrium. I thought the answer would be decreasing the pressure, but then it would make the reaction proceeding backwards which contradict with what the graph.

Can someone plz help me asap coz this is due tomorrow.... :P

Thankyou

But the concern of all the reactants went down as well

The system was not at equilibrium at the 5 minute mark. Lowering the pressure/increasing volume would cause the spontaneous decrease in the concentration of species as indicated.
