Answer:
6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.
Explanation:
![Rate = k[AB]^2](https://tex.z-dn.net/?f=Rate%20%3D%20k%5BAB%5D%5E2)
The order of the reaction is 2.
Integrated rate law for second order kinetic is:
Where,
is the initial concentration = 1.50 mol/L
is the final concentration = 1/3 of initial concentration =
= 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Applying in the above equation as:-


<u>6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.</u>
The correct answer is B. The difference between the orbital period of planets Mercury and Earth is 0.76 years. The orbit of mercury is the most eccentric among the planets in the Solar system and the smallest planet. It has an orbital period of 88 Earth days.
Answer:
When an electron moves from a higher to lower orbital, energy is released as waves of light.
Explanation:
The energy from the flame excites the electrons to orbitals of higher energy.
When the electrons drop to lower-energy orbitals, they release the excess energy as light waves.
