Answer: K = 284
Explanation:
Gibbs free energy (DG) = RT(InK)
Where :
R = Gas constant = 8.314J/K/mol = 0.008314KJmol/K
T = temperature in Kelvin = 298K
K = dissociation rate
DG = 14
DG = RT(InK)
14 = 0.008314 × 298 × (InK)
14 = 2.477572 × InK
Ink = (14 ÷ 2.477542)
InK = 5.6507619
K = 284
After 4-6 months but i'm happy for you
Answer:
no one can answer your question because you have shown no arrows.
The longest hydrocarbon chain in the given compound is hexane, therefore it is the parent chain to be considered with one methyl group attached to the 3rd carbon and one chloro attached on the 2nd carbon, therefore the name of the compound is 2-chloro-3-methylhexane
<span>2Al + 3Br2 -------------> 2AlBr3
</span>3 g Al = 0.11 mol Al.
<span>6 g Br2 = 0.0375 mole bromine (it is diatomic). </span>
<span>moles of aluminium will take part in reaction = 0.0375 X (2/3) = 0.025. </span>
<span>Gram-mole of AlBr3 will be produced = 0.025 mole = 6.6682 g.
</span>moles of Al left = 0.11 - 0.025 = 0.086<span>
