Nucular waste can take up to 5-10 years until it is "safe" to be around
We know that reate constant (-Ea/RT)
K = Ae^(-Ea/RT)
A = frequency factor
Ea = activation energy
R = constant
T = temperature
Let us take two rate constants
<span>K1 = Ae^(Ea1/RT) </span>
K2 = Ae^-(Ea2/RT)
K2 = K1/H
<span>H = e^ (Ea2/RT - Ea1/RT)</span>
1.386 = 1/RT (Ea2 – HG Kj/mol)
<span>Substituting everything to the equation, we get 3.43 kJ/mol</span>
I hope this helps the answer is A
If an orderly set of steps is followed, the observations and results are more reliable.
