The reaction between calcium carbonate (CaCO3) and HCl produces calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O).
Lisa [10]

When the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster.

<h3>What is the rate of a reaction?</h3>

The rate of a reaction is how fast a chemical reaction occurs i.e. the conversion of reactants to products.

The rate of a chemical reaction can be influenced by certain factors including the concentration of reactants.

The more the concentration of a reactant, the more the collision between the reactants and hence, the faster the reaction will proceed.

Therefore, when the hydrogen chloride concentration doubles, the number of collisions between the reactants becomes increased, which causes the rate of the forward reaction to be faster

What is normality in chemistry?​
Advocard [28]

Answer:

a measure of concentration equal to the gram equivalent weight per liter of solution.

Explanation:

Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute's role in the reaction determines the solution's normality. Normality is also known as the equivalent concentration of a solution.
