Answer:
<h2>Volume = 9.29 mL</h2>Explanation:
Density of a substance can be found by using the formula
From the question
Density = 11.3 g/mL
mass = 105 g
Substitute the values into the above formula and solve for the volume
That's
Cross multiply
11.3v = 105
Divide both sides by 11.3
v = 9.29203
We have the final answer as
<h3>Volume = 9.29 mL</h3>Hope this helps you
Answer: The activation energy Ea for this reaction is 22689.8 J/mol
Explanation:
According to Arrhenius equation with change in temperature, the formula is as follows.
= rate constant at temperature
=
= rate constant at temperature
=
= activation energy = ?
R= gas constant = 8.314 J/kmol
= temperature =
= temperature =
Putting in the values ::
The activation energy Ea for this reaction is 22689.8 J/mol
