Front

What is the order of a reactant if doubling its concentration results in the rate of the reaction doubling?

Back

First order reactant.

Front

What does Ea stand for in chemistry?

Back

Ea stands for activation energy, which is the minimum energy required for a reaction to occur.

Front

Which factor does NOT increase the rate of a reaction?

Back

Placing the reactant vessel in a freezer.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the effect of increasing the temperature on the rate of a reaction?

Back

Increasing the temperature generally increases the rate of a reaction.

Front

What is a termolecular reaction?

Back

A termolecular reaction involves three molecules colliding in a single reaction event.

Front

What happens to the reaction rate when the concentration of reactants is increased?

Back

The reaction rate typically increases.

Front

What is the effect of decreasing the pressure in a gaseous reaction?

Back

Decreasing the pressure generally slows down the reaction rate.

Front

What is the relationship between surface area and reaction rate?

Back

Increasing the surface area of a solid reactant increases the reaction rate.

Front

What is the role of temperature in chemical reactions?

Back

Temperature affects the kinetic energy of molecules, influencing the frequency and energy of collisions.
