Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,


Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.


Substitute the values then we get


Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
the solution for the inequalities 5m - 2 ≤-14 or -2m ≤ -15 is m ≤ - 2.4 or m ≥ 7.5.
First inequality:
5m - 2 ≤ - 14
Add 2 to both the sides:
5 m - 2 + 2 ≤ - 14 + 2
5 m ≤ - 12
Divide both sides by 5:
5 m / 5 ≤ - 12 / 5
m ≤ - 2.4
Other inequality:
-2m ≤ -15
Divide both sides by 2:
-m ≤ -7.5
m ≥ 7.5
So, we get:
m ≤ - 2.4 or m ≥ 7.5
Therefore, we get that, the solution for the inequalities 5m - 2 ≤-14 or -2m ≤ -15 is m ≤ - 2.4 or m ≥ 7.5.
