Critical Pressure given Van der Waals Constants Solution

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

FIRST Step Consider the formula

P c = (\frac{a}{27 \cdot {(b)}^{2}})

Next Step Substitute values of Variables

∴

P c = (\frac{2Pa*kL²/mol²}{27 \cdot {(3L/mol)}^{2}})

Next Step Convert Units

∴

P c = (\frac{2Pa*kL²/mol²}{27 \cdot {(0.003m³/mol)}^{2}})

Next Step Prepare to Evaluate

∴

P c = (\frac{2}{27 \cdot {(0.003)}^{2}})

Next Step Evaluate

∴

P c = 8230.45267489712Pa

LAST Step Rounding Answer

∴

P c = 8230.4527Pa
