Say we have a chemical reaction (in equilibrium obviously (<->)):

A (s) <-> B(g) + C(g)

I know that Kpressure = Kconcentration*[(R)(T)]^(delta)n

The question involves the (delta)n (number of moles)

(delta)n = ( #moles in product - #moles in reactant)

Well due to pure solids not being included in Kpressure or Kconcentration and Kpressure equaling:

Kpressure = Pressure(b) * Pressure(c)

Would

(delta)n = 2 - 1 = 1

even though A (pure solid) is not included in Kconcentration or Kpressure?
