Final Rate Expression for Straight Mass Transfer Solution

Follow our step by step solution on how to calculate Final Rate Expression for Straight Mass Transfer?

FIRST Step Consider the formula

r'''' A = (\frac{1}{(\frac{1}{k Ag} \cdot a) + (\frac{H A}{k Al} \cdot a)}) \cdot (p A - H A \cdot C A)

Next Step Substitute values of Variables

∴

r'''' A = (\frac{1}{(\frac{1}{1.234m/s} \cdot 0.11m⁻¹) + (\frac{0.7888mol/(m³*Pa)}{3.298m/s} \cdot 0.11m⁻¹)}) \cdot (19Pa - 0.7888mol/(m³*Pa) \cdot 24.1mol/m³)

Next Step Prepare to Evaluate

∴

r'''' A = (\frac{1}{(\frac{1}{1.234} \cdot 0.11) + (\frac{0.7888}{3.298} \cdot 0.11)}) \cdot (19 - 0.7888 \cdot 24.1)

Next Step Evaluate

∴

r'''' A = -0.087310309853663mol/m³*s

LAST Step Rounding Answer

∴

r'''' A = -0.0873mol/m³*s
