Question

The decomposition of hydrocarbon follows the equation k = (4.5 × 1011 s−1) e−28000 K/T Calculate Ea.

Answer 1

Hey Dear,

◆ Answer -

Ea = 232.792 kJ/mol

● Explaination -

Given equation is -

k = 4.5×10^11 s⁻¹ × e^(−28000K/T)

Comparing it with standard form of Arrhenius equation k = A.e^(-Ea/RT)

Ea/RT = 28000K/T

Ea = R × 28000 K

Substituting values,

Ea = 232792 J/mol

Ea = 232.792 kJ/mol

Therefore, activation energy for decomposition of hydrocarbon is 232.792 kJ/mol.

Hope this helps you.
