-Refer to Exhibit 14-5. What equilibrium expression shown below would allow you to solve for x and therefore enable you to solve for the equilibrium concentrations of each of the substances present at equilibrium?

• A) x³/(0.15 - x)² = 9.30×10 ^{- 8}
• B) 4x³/(0.15 - 2x)² = 9.30×10 ^{- 8}
• C) 2x³/(0.15 - 2x)² = 9.30×10 ^{- 8}
• D) 4x³/(0.15 - x)² = 9.30×10 ^{- 8}
• E) 2x³/(0.15 + 2x)² = 9.30×10 ^{- 8}
