<span>Saturated sodium chloride
is used to transfer the product rather than water since it is not polar and
rinsing the product with water would revert any 4-methylcyclohexene back to
4-methylcyclohexanol in the Hickman Head and thus lowering the percent yield;
using water would shift the equilibrium towards the reactants. Also
sodium chloride removes the small amount of phosphoric acid and also a small
amount of water. If one were to add water, both 4-methylcyclohexene and
phosphoric acid are partially soluble making difficult to remove the water
later; sodium chloride makes the water less reactive so easier to remove by
making the aqueous later more polar.</span>
Answer:
The activation energy is 164.02 kJ/mol
Explanation:
Log (k2/k1) = Ea/2.303R × [1/T1 - 1/T2]
k1 = 8.9×10^-4 s^-1
k2 = 9.83×10^-3 s^-1
R = 8.314 J/mol.K
T1 = 540 K
T2 = 578 K
Log (9.83×10^-3/8.9×10^-4) = Ea/2.303×8.314 × [1/540 - 1/578]
1.043 = 6.359×10^-6Ea
Ea = 1.043/6.359×10^-6 = 164020 J/mol = 164020/1000 = 164.02 kJ/mol
