Answer: 365 K
Explanation:
According to the Arrhenius equation,
or,
where,
= rate constant at = 1.00
= rate constant at = 5.00
= activation energy for the reaction = 28.90 kJ/mol= 28900 j/mol
R = gas constant = 8.314 J/mole.K
= initial temperature = 313 K
= final temperature = ?
Now put all the given values in this formula, we get
Therefore, 365 K is required to increase the reaction rate by 5.00 times.
Answer:
Explanation:
Protozoa and Bacteria: Protozoa are very small one-celled creatures. They play an important role in helping to make the soil better by feeding on bacteria and releasing excess nitrogen, which is really good for plants. Bacteria are among the tiniest and most numerous organisms in the soil.
Answer:
A. Move to safe location
Explanation:
Plants and animals form the living community of the environment. Both of them share some of the common characteristics. Both are made of cells and they use energy for their growth and development. One of the differences between the two lies in the ability to move from one place to another. Animals have legs with which they can easily move from one place to another in search of food, shelter, and safety. While plants are unable to move as they are fixed in one place.
We can use the combined gas law equation to find the new pressure of the gas.
where P - pressure
V - volume
T - temperature
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
P1 - 795 mm Hg x 0.0013 atm/ mm Hg = 1.033 atm
T1 - 23.5 °C + 273 = 296.5 K
T2 - 31.7 °C + 273 = 304.7 K
substituting the values in the equation
P = 0.712 atm
the answer closest to this value is A) 0.723 atm
therefore answer is
<span>A) 0.723 atm</span>
