It will take 21.57min for the concentration of A to reach
0.080 M if The kinetics of a gas phase reaction of the form A → Products results
The kinetic concept of gases is an easy, historically tremendous classical version of the thermodynamic conduct of gases, with which many major principles of thermodynamics had been installed. gasoline kinetics is technological know-how in the department of fluid dynamics, worried with the take a look at of motion of gases and their outcomes on physical systems. based on the principles of fluid mechanics and thermodynamics, gasoline dynamics arises from the studies of fuel flows in transonic and supersonic flights.
Unit of rate constants for
0 order reaction = M/s
1st order reaction = sec-1
2nd order reaction = M-1s-1
So, this reaction is a 0-order reaction because it's rate constant has a unit M/min
Now half-life of 0 order reaction = Ao/2K
Where Ao = initial concentration
K = rate constant
using kinetics of a gas
Given,
Ao = 0.337M and K = 0.00781M/min
Putting all the values we get
t1/2 = 0.337/2×0.00781 min
On calculating
t1/2 = 21.57min

Answer:
1.36 g.
Explanation:
First we calculate the molar mass of sodium acetate trihydtrate:
CH3COONa.3H2O
= 12 + 3 + 12 + 2*16 + 23 + 6 + 3*16
= 136 g.
So 1 L of 1 M solution contains 136 g
0.100 M solution will contain 13.6 g
100 mL of 0.100 M solution contains 1.36 g.
