Critical Pressure without use of Van der Waals Constants Solution

Follow our step by step solution on how to calculate Critical Pressure without use of Van der Waals Constants?

FIRST Step Consider the formula

P c = (\frac{3}{8}) \cdot (\frac{[R] \cdot T c}{V cr})

Next Step Substitute values of Variables

∴

P c = (\frac{3}{8}) \cdot (\frac{[R] \cdot 647K}{5L})

Next Step Substitute values of Constants

∴

P c = (\frac{3}{8}) \cdot (\frac{8.3145 \cdot 647K}{5L})

Next Step Convert Units

∴

P c = (\frac{3}{8}) \cdot (\frac{8.3145 \cdot 647K}{0.005m³})

Next Step Prepare to Evaluate

∴

P c = (\frac{3}{8}) \cdot (\frac{8.3145 \cdot 647}{0.005})

Next Step Evaluate

∴

P c = 403459.298545886Pa

LAST Step Rounding Answer

∴

P c = 403459.2985Pa
