Open Ended

Determine the molarity of Q₂, Z₂, and QZ at equilibrium

Multiple Choice

Write the equilibrium constant expression in terms of molarity

• $$K\ =\ \frac{\left[Q_2\right]\left[Z_2\right]}{\left[QZ\right]}$$

• $$K\ =\ \frac{\left[Q_2\right]\left[Z_2\right]}{\left[QZ\right]^2}$$

• $$K\ =\ \frac{\left[QZ\right]}{\left[Q_2\right]\left[Z_2\right]}$$

• $$K\ =\ \frac{\left[QZ\right]^2}{\left[Q_2\right]\left[Z_2\right]}$$
