I think it is A. The reaction rates can change.
I think we all know that B. and C. are incorrect, but I took a science lesson about this and it specifically said that on a graph of a rate, a curved line is NOT constant, meaning it is possible to not be constant.
Increases
Stays the same
s-orbitals
d-orbitals
p-orbitals
Explanation:
The trend in the electronic configuration on the periodic table follows a definite pattern because the arrangement of elements on the table is based on the periodic law.
The periodic law states that "The properties of elements are a function of their atomic number".
- Elements in the same horizontal period have increasing number of valence electrons.
- The number of valence electrons stays the same down a group.
- Groups 1 and 2 are known as the s-block and electrons are added to the s-orbitals for them.
- Groups 3 to 12 is the transition block and electrons the valence d-orbital.
- Groups 3 through 18 is the p-block where the valence shell is the p-orbital.
