Kp and Equilibrium Composition of Ideal Gases
16-1C No, the wooden table is NOT in chemical equilibrium with the air. With proper catalyst, it will reach with the oxygen in the air and burn.
16-2C They are

∆ν
where ∆ν = ν C + ν D −ν A −ν B . The first relation is useful in partial pressure calculations, the second in determining the Kp from gibbs functions, and the last one in equilibrium composition calculations.
16-3C (a) No, because Kp depends on temperature only.
(b) In general, the total mixture pressure affects the mixture composition. The equilibrium constant for the reaction
