Critical Temperature of Real Gas using Wohl Equation given Reduced and Critical Parameters Solution

Follow our step by step solution on how to calculate Critical Temperature of Real Gas using Wohl Equation given Reduced and Critical Parameters?

FIRST Step Consider the formula

T' c = \frac{\frac{[R]}{((P r \cdot P, c) + (\frac{a}{(V' r \cdot V' c) \cdot ((V' r \cdot V' c) - b)}) - (\frac{c}{({(V' r \cdot V' c)}^{3})})) \cdot ((V' r \cdot V' c) - b)}}{T r}

Next Step Substitute values of Variables

∴

T' c = \frac{\frac{[R]}{((0.0024 \cdot 4.6E+6Pa) + (\frac{266}{(246.78 \cdot 0.0025m³/mol) \cdot ((246.78 \cdot 0.0025m³/mol) - 0.0062)}) - (\frac{21}{({(246.78 \cdot 0.0025m³/mol)}^{3})})) \cdot ((246.78 \cdot 0.0025m³/mol) - 0.0062)}}{1.46}

Next Step Substitute values of Constants

∴

T' c = \frac{\frac{8.3145}{((0.0024 \cdot 4.6E+6Pa) + (\frac{266}{(246.78 \cdot 0.0025m³/mol) \cdot ((246.78 \cdot 0.0025m³/mol) - 0.0062)}) - (\frac{21}{({(246.78 \cdot 0.0025m³/mol)}^{3})})) \cdot ((246.78 \cdot 0.0025m³/mol) - 0.0062)}}{1.46}

Next Step Prepare to Evaluate

∴

T' c = \frac{\frac{8.3145}{((0.0024 \cdot 4.6E+6) + (\frac{266}{(246.78 \cdot 0.0025) \cdot ((246.78 \cdot 0.0025) - 0.0062)}) - (\frac{21}{({(246.78 \cdot 0.0025)}^{3})})) \cdot ((246.78 \cdot 0.0025) - 0.0062)}}{1.46}

Next Step Evaluate

∴

T' c = 0.000799986364703682K

LAST Step Rounding Answer

∴

T' c = 0.0008K
