5.04 Discussion: Reaction-Rate Factors
saul85 [17]

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.
