Second Stability Constant Solution

Follow our step by step solution on how to calculate Second Stability Constant?

FIRST Step Consider the formula

K 2 = \frac{n factor \cdot (n second_stability - 1) \cdot k 1 \cdot L}{L \cdot L \cdot (2 - n factor) \cdot k 1}

Next Step Substitute values of Variables

∴

K 2 = \frac{0.5 \cdot (1.5 - 1) \cdot 2.5 \cdot 0.55}{0.55 \cdot 0.55 \cdot (2 - 0.5) \cdot 2.5}

Next Step Prepare to Evaluate

∴

K 2 = \frac{0.5 \cdot (1.5 - 1) \cdot 2.5 \cdot 0.55}{0.55 \cdot 0.55 \cdot (2 - 0.5) \cdot 2.5}

Next Step Evaluate

∴

K 2 = 0.303030303030303

LAST Step Rounding Answer

∴

K 2 = 0.303
