Rate of Reaction

Front

What is the rate of reaction?

Back

The rate of reaction is the speed at which reactants are converted into products in a chemical reaction.

Front

What factors affect the rate of a chemical reaction?

Back

The rate of a chemical reaction can be affected by temperature, concentration of reactants, particle size (surface area), and the presence of catalysts.

Front

How does temperature affect the rate of reaction?

Back

Increasing the temperature generally increases the rate of reaction because particles move faster and collide more often.

Front

What is the effect of concentration on the rate of reaction?

Back

Higher concentration of reactants leads to more frequent collisions, thus increasing the rate of reaction.

Front

Why does smaller particle size increase the rate of reaction?

Back

Smaller particle size increases the surface area exposed for the reaction, allowing more collisions to occur.

Front

What is a chemical reaction?

Back

A chemical reaction is a process where substances (reactants) are transformed into different substances (products) through the breaking and forming of bonds.

Front

What indicates that a chemical reaction has occurred?

Back

Signs of a chemical reaction include color change, temperature change, gas production, and the formation of a precipitate.

Front

What is a precipitate?

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What happens to the temperature of a solution when an exothermic reaction occurs?

Back

In an exothermic reaction, the temperature of the solution increases as heat is released.

Front

What happens to the temperature of a solution when an endothermic reaction occurs?

Back

In an endothermic reaction, the temperature of the solution decreases as heat is absorbed.
