When all reactants and products have the same physical state, then the reaction is called
Heterogeneous equilibrium
Homogeneous equilibrium
What are [A] and [B]?
Concentration of reactants.
Concentration of products.
Energy of reactants.
Energy of products.
The square brackets in a Kc expression represent ?
concentration
concentration in mol L-1
concentration in g L-1
the same as round brackets
What is the equilibrium expression for:
Fe3O4(s) + 4H2(g) <=> 3Fe(s) + 4H2O(g)
Kc =
[Fe]3 [H2O]4 / [Fe3O4] [H2]4
[Fe3O4] [H2]4 / [Fe]3 [H2O]4
[H2O]4 / [H2]4
[Fe] [H2O] / [Fe3O4] [H2]
What is the equilibrium-constant expression for
CO2(g) + H2(g) ↔ CO(g) + H2O(l)
Kp= (PCO)(PH2O) / (PCO2)(PH2)
Kp= (PCO2)(PH2) / (PCO)
Kp= (PCO2)(PH2) / (PCO)(PH2O)
Kp= (PCO) / (PCO2)(PH2)
Consider the following reaction. What would be the equilibrium constant expression?
4Br2(g) + CH4(g) ↔ 4HBr(g) + CBr4(g)
Kc = [Br2]4 [CH4]/ [HBr]4 [CBr4]
Kc = [HBr]4 [CBr4]/ [Br2]4 [CH4]
Kc = [HBr ]/ [Br2]4 [CH4]
Kc = [HBr]4 [CBr4]/ [Br2]4 [CH]4
What is the reaction/equation for this Kc expression
2N2 + O2 ⇌ 2NO
N2 + O2 ⇌ NO
NO ⇌ 2NO
N2 + O2 ⇌ 2NO
