Factors that Affect the Rate of Reaction Flashcards

All 6 cards in this deck

List the five factors that affect the rate of a chemical reaction.

Concentration of reactants in solution, pressure of reacting gases, surface area of solid reactants, temperature, and the presence of a catalyst.

What effect does increasing the temperature have on the rate of a reaction?

It increases the rate of reaction.

What effect does breaking a solid reactant into smaller pieces have on the rate of reaction?

It increases the rate, because the surface area of the solid is increased.

What effect does increasing the pressure of reacting gases have on the rate of reaction?

It increases the rate of reaction.

True or false? Doubling the concentration of a reactant in solution roughly doubles the rate of reaction.

True. There are twice as many reactant particles in the same volume, so roughly twice the collision frequency.

True or false? Using smaller pieces of the same mass of a solid reactant increases the total mass of product formed.

False. The same amount of product is formed, just in a shorter time.
