Pressure in nernst equation
« on: January 16, 2006, 04:46:10 PM »
I read that pressure is supposed to be a factor that can be taken into account in the nernst equation. Does anyone know where it is in the equation?

Take a look at the first form of the Nernst equation - it contains ln(Q), where Q is reaction quotient. For
reaction like

2H+ + 2e- -> H2

Q = pH2/[H+ ]2

That's where the pressure goes.
