RICE table
1. With the following condensation reaction, calculate the equilibrium concentration for
C2H5OH. Given [C4H7OOH]initial = 0.590M, [C2H5OH]initial = 0.450M, and Keq = 4.69
C4H7OOH(aq) + C2H5OH(aq)  C4H7OOC2H5(aq) + H2O(l)
2. Calculate the initial concentration of [NH3].
Given: [Ag+]initial = 0.0100M, [Ag(NH3)2+]equilibrium = 0.00278M, and Keq = 7.99.
Ag+ (aq) + 2NH3 (aq)  Ag(NH3)2+ (aq)
3. Calculate the equilibrium concentration for I2.
Given: [H2]initial = 0.25M, [I2]initial = 0.25M, [HI]initial = 1.2M and K = 54
H2(s) + I2(aq)  2HI(g)
4. This is a dissociation reaction of acetic acid (a weak acid). With K = 1.76 x 10-5 and
[CH3COOH] = 1.6 x 10-4, determine the equilibrium concentration for [H3O+].
CH3COOH(aq) + H2O(l)  CH3COO- (aq)+ H3O+(aq)
