Remember that
- For being a bond covalent ∆E<1.8
- For being a bond ionic ∆E>1.8

Increasing the surface area of the reactant by pelletizing the calcium carbonate, and increasing the concentration of hydrochloric acid resulted in increase in the rate of reaction.
<h3>What is reaction rate?</h3>
Reaction rate refers to the rate at which reactant molecules are consumed or the rate at which product molecules are formed.
The factors that affect reaction rate include:
- Temperature
- Concentration
- Surface area of reactants
- Nature of reactants
- Presence of catalysts
Given an experiment to determine effect of surface area of reactants and concentration on reaction rate of dilute hydrochloric acid and calcium carbonate:
It was observed that increasing the surface area of the reactant by pelletizing the calcium carbonate and increasing the concentration of hydrochloric acid made the reaction proceed faster.
In conclusion, reaction rate increases with increase in surface area.

Answer: observe the rate of the reaction and then observe it again with the catalyst included.
Explanation:
Rate of the reaction is determined by how fast reactants change into products.
The reactants must possess a minimum amount of energy called as activation energy to cross the energy barrier and convert to products.
A catalyst is a substance which when added to a chemical reaction, increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst thus increases the rate of reaction.

Again please specify your question, you still haven't indicated what you want to be solved.
by formula units I assume you mean atoms?
I'll edit my answer accordingly if you could specify down in the comments.
