The expression of the reaction rate can be obtained assuming that the reaction follow a linear plot that means follow the equation y = mx + b; where m is the slope, b is the Y intercept and x and y are the variables. In order to obtain the value of the rate (the same value of the slope), we consider the velocities given in M/s and calculate the average as you can see in the image attached. Then, we write the linear plot equation with this value assuming that the Y intercept is with zero.

I'll give you a real answer later need points for test questions sorry
Answer:
Amount left after 25 days = 12.5 g
Explanation:
Given data:
Mass of sample = 400 g
Half life of sample = 5 days
Mass left after 25 days = ?
Solution:
First of all we will calculate the number of half lives passes in given time period.
Number of half lives = Time elapsed / Half life
Number of half lives = 25 days/ 5 days
Number of half lives = 5
At time zero = 400 g
At 1st half life = 400 g/2 = 200 g
At 2nd half life = 200 g/2 = 100 g
At 3rd half life = 100 g/2 = 50 g
At 4th half life = 50 g/2 = 25 g
At 5th half life = 25 g/2 = 12.5 g

Answer:
OSMOSIS
Explanation:
Osmosis (/ɒzˈmoʊ.sɪs/) is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential (region of higher solute concentration),
