Higher the concentration, the faster the reaction would occur thus higher the rate because there would be more amount of reactants for the reaction to occur and more particles would frequently collide to produce the products quickly.

Explanation:
<u>Answer:</u> Group 1 ions are known as cations and Group 17 ions are known as anions.
<u>Explanation:</u>
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. <u>For Example:</u> Fluorine is a Group 17 element which gains 1 electron to form ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. <u>For Example:</u> Sodium is a Group 1 element which looses 1 electron to form ions.
Hence, group 1 ions are known as cations and Group 17 ions are known as anions.
