Concentration of Reactant A given kf and kb Solution

Follow our step by step solution on how to calculate Concentration of Reactant A given kf and kb?

FIRST Step Consider the formula

[A] eq = \frac{k b'}{k f'} \cdot (\frac{[C] eq \cdot [D] eq}{[B] eq})

Next Step Substitute values of Variables

∴

[A] eq = \frac{0.0004L/(mol*s)}{0.0062L/(mol*s)} \cdot (\frac{19.4mol/L \cdot 0.352mol/L}{0.7mol/L})

Next Step Convert Units

∴

[A] eq = \frac{3.8E-7m³/(mol*s)}{6.2E-6m³/(mol*s)} \cdot (\frac{19400mol/m³ \cdot 352mol/m³}{700mol/m³})

Next Step Prepare to Evaluate

∴

[A] eq = \frac{3.8E-7}{6.2E-6} \cdot (\frac{19400 \cdot 352}{700})

Next Step Evaluate

∴

[A] eq = 596.691262135922mol/m³

Next Step Convert to Output's Unit

∴

[A] eq = 0.596691262135922mol/L

LAST Step Rounding Answer

∴

[A] eq = 0.5967mol/L
