Answer:
t = 21.5 min.
Explanation:
Hello!
In this case, since the kinetics of a first-order reaction is:
Thus, since we are given the 11.7 min for a 58.6-% consumption, we can compute the rate constant, k:
Now, for the second problem, as the new consumption is 80.2%, we can compute the required time as shown below:
Best regards!
Answer:
Final concentration of NaOH = 0.75 M
Explanation:
For
:-
Given mass = 90.0 g
Molar mass of NaOH = 39.997 g/mol
The formula for the calculation of moles is shown below:
Thus,
Molarity is defined as the number of moles present in one liter of the solution. It is basically the ratio of the moles of the solute to the liters of the solution.
The expression for the molarity, according to its definition is shown below as:
Where, Volume must be in Liter.
It is denoted by M.
Given, Volume = 3.00 L
So,
<u>Final concentration of NaOH = 0.75 M</u>
