Answer:
30 kJ
Explanation:
Arrhenius equation is given by:

Here, k is rate constant, A is Pre-exponential factor, Ea is activation energy and T is temperature.
taking natural log of both side
ln k = ln A - Ea/RT
In Arrhenius equation, A, R and T are constant.
Therefore,

is the lowering in activation energy by enzyme,
R = 8.314 J/mol.K
T = 37°C + 273.15 = 310 K


Answer:
The level of toxins in solutions
Answer:
See explanation
Explanation:
the Cis structure, we can have two possibilities. The methyl groups can go both in <u>axial positions</u> or both in <u>equatorial positions</u>. We have to remember that cis it means <u>"same orientation"</u>, so in the axial positions, both methyl groups go up. (Both have the same orientation). In the equatorial positions, both groups go down.
In the axial positions, we will have <u>more steric hindrance</u> because the groups are close to each other. Therefore, we will have <u>more energy</u> and the structure will be <u>less stable</u>. In the equatorial positions, we <u>dont have any steric hindrances</u>, so we will have <u>less energy and more stability</u>.
See figure 1

Communication skills were developed so knowledge could be passed along to younger generations.
<h3>How knowledge will pass through generations?</h3>
Knowledge will pass from one generation to another with the help of education. The skill people give education to their youngers about fire and tools. In this way, skills of fire and tools pass from one generation to another.
So we can conclude that communication skills were developed so knowledge could be passed along to younger generations.
