Concentration of Radical formed in Chain Reaction Solution

Follow our step by step solution on how to calculate Concentration of Radical formed in Chain Reaction?

FIRST Step Consider the formula

[R] CR = \frac{k 1 \cdot [A]}{k 2 \cdot (1 - α) \cdot [A] + k 3}

Next Step Substitute values of Variables

∴

[R] CR = \frac{70L/(mol*s) \cdot 60.5M}{0.0001L/(mol*s) \cdot (1 - 2.5) \cdot 60.5M + 60L/(mol*s)}

Next Step Convert Units

∴

[R] CR = \frac{0.07m³/(mol*s) \cdot 60500mol/m³}{1.1E-7m³/(mol*s) \cdot (1 - 2.5) \cdot 60500mol/m³ + 0.06m³/(mol*s)}

Next Step Prepare to Evaluate

∴

[R] CR = \frac{0.07 \cdot 60500}{1.1E-7 \cdot (1 - 2.5) \cdot 60500 + 0.06}

Next Step Evaluate

∴

[R] CR = 84670.3653721198mol/m³

Next Step Convert to Output's Unit

∴

[R] CR = 84.6703653721198M

LAST Step Rounding Answer

∴

[R] CR = 84.6704M
