The smallest unit that can exist as an element and still have proprieties of that element is an Atom<span />
The laws of the electrostatics were developed by Coulomb and are further detailed or subdivided into two as follows:
(1) The first one talks about the similarities in the charges of the particles and what happens to them. This states that like charges repel.
(2) The second one quantifies the field between two particles with equation showing that field is directly proportional to the masses and inversely to the square of the distance between them.
In this item, we can then say that the protons (having the same charges) will have to repel from each other in accordance to statement 1 of the law.
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.
