Backward Reaction Rate Constant for 2nd Order Opposed by 2nd Order Reaction Solution

Follow our step by step solution on how to calculate Backward Reaction Rate Constant for 2nd Order Opposed by 2nd Order Reaction?

FIRST Step Consider the formula

k b' = k f' \cdot \frac{(A 0 - x eq) \cdot (B 0 - x eq)}{{x eq}^{2}}

Next Step Substitute values of Variables

∴

k b' = 0.0062L/(mol*s) \cdot \frac{(100mol/L - 70mol/L) \cdot (80mol/L - 70mol/L)}{{70mol/L}^{2}}

Next Step Convert Units

∴

k b' = 6.2E-6m³/(mol*s) \cdot \frac{(100000mol/m³ - 70000mol/m³) \cdot (80000mol/m³ - 70000mol/m³)}{{70000mol/m³}^{2}}

Next Step Prepare to Evaluate

∴

k b' = 6.2E-6 \cdot \frac{(100000 - 70000) \cdot (80000 - 70000)}{70000^{2}}

Next Step Evaluate

∴

k b' = 3.78367346938776E-07m³/(mol*s)

Next Step Convert to Output's Unit

∴

k b' = 0.000378367346938776L/(mol*s)

LAST Step Rounding Answer

∴

k b' = 0.0004L/(mol*s)
