Forward Rate Constant in Enzymatic Reaction mechanism Solution

Follow our step by step solution on how to calculate Forward Rate Constant in Enzymatic Reaction mechanism?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

k f = \frac{20mol/L*s \cdot 10mol/L}{1.5mol/L \cdot (100mol/L - 10mol/L)}

Next Step Convert Units

∴

k f = \frac{20000mol/m³*s \cdot 10000mol/m³}{1500mol/m³ \cdot (100000mol/m³ - 10000mol/m³)}

Next Step Prepare to Evaluate

∴

k f = \frac{20000 \cdot 10000}{1500 \cdot (100000 - 10000)}

Next Step Evaluate

∴

k f = 1.48148148148148s⁻¹

LAST Step Rounding Answer

∴

k f = 1.4815s⁻¹
