Activation Energy for Zero Order Reactions Solution

Follow our step by step solution on how to calculate Activation Energy for Zero Order Reactions?

FIRST Step Consider the formula

E a = [R] \cdot T gas \cdot (\ln (A) - \ln (k))

Next Step Substitute values of Variables

∴

E a = [R] \cdot 273K \cdot (\ln (1.5E+11L/(mol*s)) - \ln (0.25mol/L*s))

Next Step Substitute values of Constants

∴

E a = 8.3145 \cdot 273K \cdot (\ln (1.5E+11L/(mol*s)) - \ln (0.25mol/L*s))

Next Step Convert Units

∴

E a = 8.3145 \cdot 273K \cdot (\ln (1.5E+8m³/(mol*s)) - \ln (250mol/m³*s))

Next Step Prepare to Evaluate

∴

E a = 8.3145 \cdot 273 \cdot (\ln (1.5E+8) - \ln (250))

Next Step Evaluate

∴

E a = 30184.4334218059J/mol

LAST Step Rounding Answer

∴

E a = 30184.4334J/mol
