Answer:
Lmol⁻¹s⁻¹
Explanation:
The rate law of the given reaction is:-
Rate=k[A][B]
Wherem, k is the rate constant.
Given that:-
Rate = 0.36 mol/Lsec = 0.36 M/sec
[A] = 3.0 M
[B] = 1.0 M
Thus,
Applying in the equation as:-
0.36 M/sec =k × 3.0 M× 1.0 M
k = 0.12 (Ms)⁻¹ = 0.12 Lmol⁻¹s⁻¹
<u>The units of k = Lmol⁻¹s⁻¹</u>
It's more dense as a liquid than as a solid. That's why ice can float in water. The answer is B.
Answer: b). The B−A−B angles between neighboring B atoms are 90∘.
Explanation: The square planar geometry is the geometry in which the four groups are connected through an angle of 90∘ and all 5 atoms are in one plane.
It is not necessary for the molecule to have two non bonding pair of electrons on atom A but if it does have , then its parent geometry will be distorted octahedral. And if it doesn't have this non bonding pair of electrons then the geometry would be the square planar.
Thus the molecule has four electron domains about the central atom A if the parent geometry is square planar otherwise it would have 8 electron domain in distorted octahedral geometry.
Answer:
The new volume of the gas is 4.74L
Explanation:
Data;
T1 = 14°C = (14 + 273.15)K = 287.15K
V1 = 4.5L
T2 = 29°C = (29 + 273.15)K = 302.15
V2 = ?
From Charles law,
The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.
Mathematically,
V = kT
k = V1 / T1 = V2 / T2 = V3 / T3 = .............= Vn / Tn.
V1 / T1 = V2 / T2
Solving for V2
V2 = (V1 * T2) / T1
V2 = (4.5 * 302.15) / 287.15
V2 = 4.735L
V2 = 4.74L
The new volume of the gas is 4.74L
