The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹
The chemical reaction :
C₂H₅Cl ------> C₂H₄(g) + HCl(g)
Determine the value and unit of the rate constant ( K )let the rate of reaction be expressed as
R = k [ C₂H₅Cl ]ⁿ ---- ( 1 )
where : n = order
k = rate constant
From the table
2 = 2ⁿ
therefore n = 1
Hence we can rewrite equation ( 1 ) as
R = k [ C₂H₅Cl ] ¹ ( first order reaction ) ---- ( 2 )
Next step : substitute the value of C₂H₅Cl and initial rate into equation 2
0.630 * 10⁻³⁰ = k ( 0.1 ) ¹ M
Therefore : K = 0.630 * 10⁻²⁹ s⁻¹
Hence we can conclude that The value of the rate constant is : 0.63 * 10⁻²⁹ s⁻¹ and The unit of the rate constant is : sec⁻¹.

Write a program that takes a date as input and outputs the date's season in the northern hemisphere. The input is a string to represent the month and an int to represent the day.
A program that takes a date as input and outputs the date's season in the northern hemisphere is; done using input as a string to represent the month and an int to represent the day.
How to Program in PythonThe seasons in the northern hemisphere are Spring, Summer, Autumn and Winter.
Now, the dates for each of these seasons are;

Answer:
11
Explanation:
The room is rectangular. The required carpet can be measured by dividing the area of the room by 12. 60 linear feet of carpet is required. Therefore, option D is correct.
What is the area of a rectangle?A rectangle is a four-sided polygon with four right angles (90-degree angles). It is a type of quadrilateral, which means it has four sides. Opposite sides of a rectangle are parallel and congruent (equal in length). The two pairs of opposite sides of a rectangle are also equal to each other.
The formula for calculating the area of a rectangle is: Area = Length x Width
Given information,
Width of the carpet = 12 feet
Now,
The area = (40 x 24) - (20 x 12)
Area = 960 - 240 = 720 square feet
The required linear feet of the carpet is:
