Explanation:
Since, it is shown that the reaction has been reversed. Therefore, value of 
will become 
.
Hence, new 
= 
= 20
Also, the number of moles of each reactant has been halved. So, 
for the reaction 
will also get halved.
Therefore, = 
= 
= 4.47
As the value of 
is given as +39.0 kJ. So, it means that the reaction is endothermic in nature. So, energy of reactants will be more than the products. Hence, according to Le Chatelier's principle reaction will move in the forward direction.
As a result, will also increase with increase in temperature.
The change in the velocity = 4 m/s
Acceleration = 4 m/s²
<h3>Further explanation</h3>
Given
vo = initial velocity = 4 m/s
vf = final velocity = 8 m/s
t = 1 s
Required
The change in the velocity
Acceleration
Solution
the change in velocity =
Acceleration = ratio of a change in velocity and the time
Input the value :
Answer:
Ranked from lowest to highest:
Sulfur - 999.6 kJ/mol
Hydrogen - 13.5984 kJ/mol
Oxygen - 13.6181 kJ/mol
Fluorine - 17.4228 kJ/mol
8 because atomic number is the same as number of protons, protons and electrons have the same amount so that the element is neither positive nor negative.
