<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of sodium bicarbonate and acetic acid is given as:

Ionic form of the above equation follows:

As, sodium and acetate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.
The net ionic equation for the above reaction follows:

Hence, the correct answer is Option C.
Answer:
increasing the number of molecules that have sufficient kinetic energy to react.
Explanation:
An increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react.
or we say; temperature increase, leads to an increase in the amount of collisions between molecules.
