Answer:
a) Eo = -C/ro + D exp(-ro/p)
1) dEN/dr = C/r² - D exp(-r/p)
2) Eo + C/ro = -Dexp(-ro/p)
C/ro = -Dexp(-ro/p) - Eo
∴ C = -ro(Dexp(-ro/p) + Eo)
3) EN = -(-ro(Dexp(-ro/p) + Eo)/r + Dexp(-r/p)
EN = ro(Dexp(-ro/p) - roEo/r + Dexp(-r/p)
EN + roEo/r = ro(Dexp(-ro/p) + Dexp(-r/p)
roEo/r = D(exp(-ro/p) + exp(-r/p) - EN
∴ Eo= r{D(exp(-ro/p) + exp(-ro/p) - EN}/ro
b)
Explanation:
Physical change!
a solid that turns into a liquid is called melting and melting is a physical change.
something like that. sorry if it’s wrong
Why chlorine has highest electron affinity than fluorine?
This is because the atomic radius increases down a group. The electron gained ends up in the outermost shell. ... Fluorine, which is higher up the group then chlorine, has a lower electron affinity. This is because the electrons in the outermost shell of a fluorine atom are closer together.
Answer:
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction
Explanation:
When we increase the temperature of one of the reactants in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases the chance of a more successful collision and the rate of reaction.
Convert 550 cm into m. Please show your work.
-From cm to m , divide by 100
-550 / 100 = 5.5m
