The following equilibria were attained at 823 K:CoO(s)+H2(g)⇌Co(s)+H2O(g) Kc=67CoO(s)+CO(g)⇌Co(s)+CO2(g) Kc=480
Based on these equilibria, calculate the equilibrium constant for H2(g)+CO2(g)⇌CO(g)+H2O(g) at 823 K.
Express your answer using two significant figures.
The following equilibria were measured at 823 K:CoO(s) + H2(g) ⇌ Co(s) + H2O(g) Kc = 67H2(g) + CO2(g) ⇌ CO(g) + H2O(g) Kc = 0.14
(a) Use these equilibria to calculate the equilibrium constant,Kc, for the reaction CoO(s) + CO(g) ⇌ Co(s)+ CO2(g)
at 823 K. (b) Based on your answer to part(a), would you say that carbon monoxide is a stronger orweaker reducing agent than H2 at T = 823 K? (c) If youwere to place 5.00 g of CoO(s) in a sealed tube with a volumeof 250 mL that contains CO(g) at a pressure of 1.00atm and a temperature of 298 K, what is the concentrationof the CO gas? Assume there is no reaction at thistemperature and that the CO behaves as an ideal gas (youcan neglect the volume of the solid). (d) If the reactionvessel from part (c) is heated to 823 K and allowed tocome to equilibrium, how much CoO(s) remains?
The following equilibria were attained at 823 K:CoO(s) + H2(g) ⇌ Co(s) + H2O(g) Kc = 67CoO(s) + CO(g) ⇌ Co(s) + CO2(g) Kc = 490Based on these equilibria, calculate the equilibrium constantfor H2(g) + CO2(g) ⇌ CO(g) + H2O(g) at 823 K.
