8 minutes and 25 seconds is the same as 8.25 in decimal form.
Divide by 60 minutes.
60 / 8.25 = 7.27 miles per hour
Best of Luck!
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.
Solvent is used to dissolve the solute in the solution
Answer: The heat moves through the atmosphere through the process of radiation.
Explanation:
There are three modes of transfer:
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
3. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards.
Thus heat moves through the atmosphere through the process of radiation
