The correct answer is option B. When the forward and reverse paths of a change occur at the same rate, <span>the system is in equilibrium specifically in dynamic equilibrium.</span> Dynamic equilibrium is
the balance in a process that is continuing. It is achieved in a reaction when
the forward rate of reaction and the backward rate of reaction is at the same
value or equal.
Explanation:
Hydrocarbon shows nonpolar
Answer:
19.91 J/K
Explanation:
The entropy is a measure of the randomness of the system, and it intends to increase in nature, thus for a spontaneous reaction ΔS > 0.
The entropy variation can be found by:
ΔS = ∑n*S° products - ∑n*S° reactants
Where n is the coefficient of the substance. The value of S° (standard molar entropy) can be found at a thermodynamic table.
S°, Cl(g) = 165.20 J/mol.K
S°, O3(g) = 238.93 J/mol.K
S°, O2(g) = 205.138 J/mol.K
So:
ΔS = (1*205.138 + 1*218.9) - (1*165.20 + 1*238.93)
ΔS = 19.91 J/K
C-Cl bond is polar.
As Cl is more electronegative than C,
Cl pulls the shared electrons towards its side making the C-Cl bond polar.
Polar meaning C gets a partial positive charge and Cl gets a partial negative charge. Thus C-Cl bond becomes polar.
CCl4 molecule is tetrahedral.
And its shape is symmetrical.
That means its similar on all corners or all planes and it can be cut into equal halves from any plane.
C-Cl bond is polar.But the C-Cl polairty gets cancelled out as its pulled equally from all sides.
Since the molecule is symmetrical CCl4 is non polar.
