Dissociation Constant Ka given Initial Concentration of Weak Acid and Degree of Dissociation Solution

Follow our step by step solution on how to calculate Dissociation Constant Ka given Initial Concentration of Weak Acid and Degree of Dissociation?

FIRST Step Consider the formula

K a = \frac{C 0 \cdot (𝝰^{2})}{1 - 𝝰}

Next Step Substitute values of Variables

∴

K a = \frac{0.3mol/L \cdot ({0.35}^{2})}{1 - 0.35}

Next Step Convert Units

∴

K a = \frac{300mol/m³ \cdot ({0.35}^{2})}{1 - 0.35}

Next Step Prepare to Evaluate

∴

K a = \frac{300 \cdot ({0.35}^{2})}{1 - 0.35}

Next Step Evaluate

∴

K a = 56.5384615384615

LAST Step Rounding Answer

∴

K a = 56.5385
