Which of the following changes will slow down a reaction?
1 answer:
Answer: Option (d) is the correct answer.
Explanation:
According to rate law, rate of a reaction is directly proportional to the concentration of reactants.
For example,
then, Rate = k [C]
Therefore, when we decrease the concentration of the reactant then there will also be decrease in the rate of a reaction.
Whereas when we increase the temperature then there is increase in rate of reaction due to increase in kinetic energy of molecules.
Thus, we can conclude that decreasing the concentration of the reactant will slow down a reaction.

Answer:
For the Ag ground-state ion, the type of orbital from which an electron will need to be removed to form the ion of greater positive charge is :
<u>s-orbital</u>
Explanation:
Naming of orbitals :
s = s-orbital
p = p-orbital
d = d-orbital
The electronic configuration of Ag is :
The Outermost shell = 5s
so electron should be removed from 5s . there is only 1 electron in 5s -shell. Hence , Ag exist +1 oxidation state.
According to Aufbau's Rule : Electron will be filled first in lower energy orbital.
The electron should be removed first ,from the higher energy orbital.This is because high energy orbitals are away from the nucleus and can be easily removed. The outermost electron feel less attraction of the nucleus
Ionization energy : Energy required to remove the electron from the outermost shell of the element in the gaseous state.
Hence it will form Ag+ cation
<u>Ag+:</u>
Outer shell is removed after loss of electron.
