One of the forms of Arrhenius equation :
ln(k₁/k₂) = -(Eₐ/R)[(1/T₁) - (1/T₂)]
ln(0.00000000951/0.0000110) = -( Eₐ/8.314)[(1/500) - (1/600)]
Eₐ = -8.314 × ln(0.00000000951/0.0000110) ÷ [(1/500) - (1/600)] J/mol
Eₐ = 176000 J/mol
Eₐ = 176 kJ/mol
ln(k₁/k₂) = -(Eₐ/R)[(1/T₁) - (1/T₂)]
ln(0.00000000951/0.0000110) = -( Eₐ/8.314)[(1/500) - (1/600)]
Eₐ = -8.314 × ln(0.00000000951/0.0000110) ÷ [(1/500) - (1/600)] J/mol
Eₐ = 176000 J/mol
Eₐ = 176 kJ/mol
