Change in Pressure using Clausius Equation Solution

Follow our step by step solution on how to calculate Change in Pressure using Clausius Equation?

FIRST Step Consider the formula

ΔP = \frac{∆T \cdot ΔH v}{(V m - v) \cdot T abs}

Next Step Substitute values of Variables

∴

ΔP = \frac{50.5K \cdot 11KJ/mol}{(32m³/mol - 5.5m³) \cdot 273}

Next Step Convert Units

∴

ΔP = \frac{50.5K \cdot 11000J/mol}{(32m³/mol - 5.5m³) \cdot 273}

Next Step Prepare to Evaluate

∴

ΔP = \frac{50.5 \cdot 11000}{(32 - 5.5) \cdot 273}

Next Step Evaluate

∴

ΔP = 76.784850369756Pa

LAST Step Rounding Answer

∴

ΔP = 76.7849Pa
