Here is how the Space Time for Second Order Reaction using Recycle Ratio equation looks like.

0.7314 = \frac{(0.3 + 1) \cdot 80 \cdot (80 - 20)}{80 \cdot 0.062 \cdot 20 \cdot (80 + (0.3 \cdot 20))}

0.7314s = \frac{(0.3 + 1) \cdot 80mol/m³ \cdot (80mol/m³ - 20mol/m³)}{80mol/m³ \cdot 0.062m³/(mol*s) \cdot 20mol/m³ \cdot (80mol/m³ + (0.3 \cdot 20mol/m³))}

0.7314 = \frac{(0.3 + 1) \cdot 80 \cdot (80 - 20)}{80 \cdot 0.062 \cdot 20 \cdot (80 + (0.3 \cdot 20))}

Space Time for Second Order Reaction using Recycle Ratio Solution

Follow our step by step solution on how to calculate Space Time for Second Order Reaction using Recycle Ratio?

FIRST Step Consider the formula

𝛕 = \frac{(R + 1) \cdot C o \cdot (C o - C f)}{C o \cdot k'' \cdot C f \cdot (C o + (R \cdot C f))}

Next Step Substitute values of Variables

∴

𝛕 = \frac{(0.3 + 1) \cdot 80mol/m³ \cdot (80mol/m³ - 20mol/m³)}{80mol/m³ \cdot 0.062m³/(mol*s) \cdot 20mol/m³ \cdot (80mol/m³ + (0.3 \cdot 20mol/m³))}

Next Step Prepare to Evaluate

∴

𝛕 = \frac{(0.3 + 1) \cdot 80 \cdot (80 - 20)}{80 \cdot 0.062 \cdot 20 \cdot (80 + (0.3 \cdot 20))}

Next Step Evaluate

∴

𝛕 = 0.731432858214554s

LAST Step Rounding Answer

∴

𝛕 = 0.7314s
