Could it be CaCl2➡Ca +Cl2
Answer:
is the correct answer to the given question.
Explanation:
Given k=6.40 x 10-3 min-1.
According to the first order reaction .
The concentration of time can be written as
![[\ A\ ]\ = \ [\ A_{0}\ ] * e \ ^\ {-kt}](https://tex.z-dn.net/?f=%5B%5C%20A%5C%20%5D%5C%20%3D%20%5C%20%5B%5C%20%20A_%7B0%7D%5C%20%5D%20%20%2A%20e%20%5C%20%5E%5C%20%20%7B-kt%7D)
Here ![[\ A\ ]_{0}](https://tex.z-dn.net/?f=%5B%5C%20A%5C%20%5D_%7B0%7D)
= Initial concentration.
So ![[\ A\ ]_{0}= 0.0314 M](https://tex.z-dn.net/?f=%5B%5C%20A%5C%20%5D_%7B0%7D%3D%200.0314%20M)
Putting this value into the above equation.
=0.211 M
This can be written as
The correct response is A. The inner she'll contains 2 electrons and the outer shell contains 4 electrons.
Answer:
4.3 × 10⁻⁵ M s⁻¹
Explanation:
Step 1: Given data
- Rate constant (k): 2.20 × 10⁷ M⁻¹s⁻¹
- Concentration of NO ([NO]): 3.3 × 10⁻⁶ M
- Concentration of O₃ ([O₃]): 5.9 × 10⁻⁷ M
- First order with respect to both NO and O₃
Step 2: Write the balanced reaction
NO + O₃ ⇒ NO₂ + O₂
Step 3: Calculate the reaction rate
The rate law is:
rate = k × [NO] × [O₃]
rate = 2.20 × 10⁷ M⁻¹s⁻¹ × 3.3 × 10⁻⁶ M × 5.9 × 10⁻⁷ M
rate = 4.3 × 10⁻⁵ M s⁻¹
