Reverse Rate Constant in Enzymatic Reaction Mechanism Solution

Follow our step by step solution on how to calculate Reverse Rate Constant in Enzymatic Reaction Mechanism?

FIRST Step Consider the formula

k r = \frac{k f \cdot S \cdot ([E 0] - ES)}{ES}

Next Step Substitute values of Variables

∴

k r = \frac{6.9s⁻¹ \cdot 1.5mol/L \cdot (100mol/L - 10mol/L)}{10mol/L}

Next Step Convert Units

∴

k r = \frac{6.9s⁻¹ \cdot 1500mol/m³ \cdot (100000mol/m³ - 10000mol/m³)}{10000mol/m³}

Next Step Prepare to Evaluate

∴

k r = \frac{6.9 \cdot 1500 \cdot (100000 - 10000)}{10000}

Next Step Evaluate

∴

k r = 93150mol/m³*s

LAST Step Convert to Output's Unit

∴

k r = 93.15mol/L*s
