Q: A reaction rate has a constant of 1.23 x 10-4/s at 28 degrees C and 0.235 at 79 degrees C. Determine the activation barrier for the reaction.
A: My work thus far:
ln(1.23 x 10-4/0.235)=(Ea/8.314)(1/79-1/28)
2,723 J/mol = 0.002723 kJ/mol
My answer is incorrect, and I would like to know where I went wrong and what the correct answer is.
Thanks for showing your work.
I didn't work it out but your error is you didn't convert T to kelvin.
28 C = 301.15
79 C = 352.15
