Activation Energy for Second Order Reaction Solution

Follow our step by step solution on how to calculate Activation Energy for Second Order Reaction?

FIRST Step Consider the formula

E a = [R] \cdot T Kinetics \cdot (\ln (A factor) - \ln (K second))

Next Step Substitute values of Variables

∴

E a = [R] \cdot 85K \cdot (\ln (20L/(mol*s)) - \ln (0.51L/(mol*s)))

Next Step Substitute values of Constants

∴

E a = 8.3145 \cdot 85K \cdot (\ln (20L/(mol*s)) - \ln (0.51L/(mol*s)))

Next Step Convert Units

∴

E a = 8.3145 \cdot 85K \cdot (\ln (0.02m³/(mol*s)) - \ln (0.0005m³/(mol*s)))

Next Step Prepare to Evaluate

∴

E a = 8.3145 \cdot 85 \cdot (\ln (0.02) - \ln (0.0005))

Next Step Evaluate

∴

E a = 2593.04418017523J/mol

LAST Step Rounding Answer

∴

E a = 2593.0442J/mol
