Critical Temperature given Van der Waals Constants Solution

Follow our step by step solution on how to calculate Critical Temperature given Van der Waals Constants?

FIRST Step Consider the formula

T c = \frac{8 \cdot a}{27 \cdot b \cdot [R]}

Next Step Substitute values of Variables

∴

T c = \frac{8 \cdot 2Pa*kL²/mol²}{27 \cdot 3L/mol \cdot [R]}

Next Step Substitute values of Constants

∴

T c = \frac{8 \cdot 2Pa*kL²/mol²}{27 \cdot 3L/mol \cdot 8.3145}

Next Step Convert Units

∴

T c = \frac{8 \cdot 2Pa*kL²/mol²}{27 \cdot 0.003m³/mol \cdot 8.3145}

Next Step Prepare to Evaluate

∴

T c = \frac{8 \cdot 2}{27 \cdot 0.003 \cdot 8.3145}

Next Step Evaluate

∴

T c = 23.7575022306619K

LAST Step Rounding Answer

∴

T c = 23.7575K
