Reverse Rate Constant given Michaelis Constant Solution

Follow our step by step solution on how to calculate Reverse Rate Constant given Michaelis Constant?

FIRST Step Consider the formula

k r = (K M \cdot k f) - k cat

Next Step Substitute values of Variables

∴

k r = (3mol/L \cdot 6.9s⁻¹) - 0.65s⁻¹

Next Step Convert Units

∴

k r = (3000mol/m³ \cdot 6.9s⁻¹) - 0.65s⁻¹

Next Step Prepare to Evaluate

∴

k r = (3000 \cdot 6.9) - 0.65

Next Step Evaluate

∴

k r = 20699.35mol/m³*s

Next Step Convert to Output's Unit

∴

k r = 20.69935mol/L*s

LAST Step Rounding Answer

∴

k r = 20.6994mol/L*s
