The HI decomposition reaction
2HI —》H2 + I2
Ea = 182kj/mole
And at 700 degree c , the rate constant is 1.57x 10-3 M-1S-1
What is the rate constant at the 600 degree c?
I use log k2/k1 = -Ea/Rx2.303 (1/T2 - 1/T1)
But the answer is wrong
Answer is 1.19x10-3 M-1S-1
Thanks

For the decomposition of hydrogen iodide, 2HI → H2 + I2, the rate constant is 9.51×10-9 M-1s-1 at 500 K and 1.10×10-5M-1s-1 at 600 K. What is the value of the activation energy, Ea, in kJ/mol?

The activation energy of a certain reaction is 37.6 kJ/mol . At 21 ∘C , the rate constant is 0.0190s^-1 . At what temperature in degrees Celsius would this reaction go twice as fast?

Please, use Arrchenius eqn. :
lnk2/k1=Ea/R (1/T1-1/T2)
We are looking for T2? , but how do I know what is k2 when only k1 is given as 0.0190s^-1
