Answer : The mass of dissolved will be, 0.2365 grams
Explanation :
First we have to calculate the concentration of .
As we know that,
where,
= concentration of = ?
= partial pressure of = 1.65 atm
= Henry's law constant =
Now put all the given values in the above formula, we get:
The concentration of =
Now we have to calculate the moles of
Now we have to calculate the mass of
Therefore, the mass of dissolved will be, 0.2365 grams
The given question is incomplete. The complete question is as follows.
The enzyme urease catalyzes the reaction of urea, (), with water to produce carbon dioxide and ammonia. In water, without the enzyme, the reaction proceeds with a first-order rate constant of at . In the presence of the enzyme in water, the reaction proceeds with a rate constant of at .
If the rate of the catalyzed reaction were the same at as it is at , what would be the difference in the activation energy between the catalyzed and uncatalyzed reactions?
Express your answer using two significant figures.
Explanation:
The reaction equation is as follows.
Urea + Water
Hence, it is given that,
without enzyme: Rate = at
with enzyme: Rate = at
Rate = at
It is known that,
ln \frac{K_{2}}{K_{1}} = \frac{-E_{a}}{R}{\frac{1}{T_{2}} - \frac{1}{T_{1}}][/tex]
and, ln K =
Let us assume that collision factor (A) is same for both the reactions.
Hence,
=
= 63672.8 J/mol
= 63.67 kJ/mol (as 1 kJ = 1000 J)
Thus, we can conclude that the difference in the activation energy between the catalyzed and uncatalyzed reactions is 63.67 kJ/mol.
Answer:
Theory of Plate Tectonics
Explanation:
Scientists especially Geologists study and record seismic data and volcanic activities in order to support the theory of plate tectonics.
The theory of plate tectonics suggests that the earth is broken into slabs called the lithosphere that moves over the fluid asthenosphere below.
- The use of seismic data presents scientists with a way of vertically looking deep into the earth.
- Volcanic activities also presents us with the kind of materials down within the earth.
- Also, coupled with this data, scientists use GPS sensors to monitor the rate of movement of the earth.
- When studying plate tectonics, it invariably culminates in the study of sea floor spreading and theory of continental drift.
