Hi, I only need help with question # 3.
Equilibrium
- Write the equilibrium expressions for the following reactions:
a) 3Fe(s) + 4H2O(g) ↔ Fe3O4(s) + 4H2(g)
b) CH3COOH(aq) + H2O(l) ↔ CH3COO-(aq) + H3O+(aq)
c) N2(g) + 3Br2(g) ↔ 2NBr3(s)
d) CaCl2(s) ↔ Ca2+(aq) + 2Cl-(aq) - Consider the following equilibrium:
CH3COOH(l) + C2H5OH(l) ↔ CH3CO2C2H5(l) + H2O(l) Keq =2.2
What must the concentration of water be for a mixture with [CH3COOH]= 0.10M, [CH3CO2C2H5]=2.0M, [C2H5OH]= 5.0M to be at equilibrium? Note: water is NOT the solvent in this reaction, therefore it will be included in the equilibrium expression.
