Concentration of Radical in Non-Stationary Chain Reactions Solution

Follow our step by step solution on how to calculate Concentration of Radical in Non-Stationary Chain Reactions?

FIRST Step Consider the formula

[R] nonCR = \frac{k 1 \cdot [A]}{- k 2 \cdot (α - 1) \cdot [A] + (k w + k g)}

Next Step Substitute values of Variables

∴

[R] nonCR = \frac{70L/(mol*s) \cdot 60.5M}{- 0.0001L/(mol*s) \cdot (2.5 - 1) \cdot 60.5M + (30.75s⁻¹ + 27.89s⁻¹)}

Next Step Convert Units

∴

[R] nonCR = \frac{0.07m³/(mol*s) \cdot 60500mol/m³}{- 1.1E-7m³/(mol*s) \cdot (2.5 - 1) \cdot 60500mol/m³ + (30.75s⁻¹ + 27.89s⁻¹)}

Next Step Prepare to Evaluate

∴

[R] nonCR = \frac{0.07 \cdot 60500}{- 1.1E-7 \cdot (2.5 - 1) \cdot 60500 + (30.75 + 27.89)}

Next Step Evaluate

∴

[R] nonCR = 72.2326238432387mol/m³

Next Step Convert to Output's Unit

∴

[R] nonCR = 0.0722326238432387M

LAST Step Rounding Answer

∴

[R] nonCR = 0.0722M
