The molar solubility of Cu(IO₃)₂ is 2.0x10^-4 at 25°C. Calculate the K_sp

• 3.3x10^-11

• 5.0x10³

• 1.4x10^-7

• 8.1x10^-5

According to the reaction shown

• Equilibrium is achieved at time (c), and the K>1

• Equilibrium is achieved at time (d), because the reaction has reached completion and is no longer moving forward or backward

• Equilibrium is achieved at time (c), and the K=1

• Equilibrium is achieved at time (b), because the rate of the forward reaction is equal to the rate of the reverse reaction

According to the graph of the reaction shown

• K>1

• K<1

• K=0

• K=1

According to the reaction

H₂(g)+Br₂(g)↔2HBr(g)

• Q=K_c the rate of the forward reaction and the reverse reaction have stopped

• Q=K_c the rate of the forward reaction and the reverse reaction are equal

• Q<K_c more HBr will be produced

• Q<K_c more H₂ and Br₂ will be produced
