PS - M19 L4 Notes Quizizz - Reaction Rates & Equilibrium

At higher temperatures, particles have more energy and move faster. As a result, they collide more (a)   . They also collide with greater energy, increasing the percentage of collisions resulting in a reaction.

Increasing the concentration of a reactant in a solution (a)   the rate of a reaction. The more reactant particles per unit volume, the greater the chance that a reaction will occur.

Increasing the pressure and decreasing the volume of a gas increases the concentration of the gas. This (a)   reaction rate.

A spoonful of granulated sugar dissolves faster than a sugar cube. The difference is surface (a)   . Dissolving is a physical change, but the same principle applies to chemical changes.

A (a)   is a substance that speeds up a chemical reaction without being permanently changed itself.

Catalysts are used in industry to speed up reactions such as (a)   production.

Inhibitors slow down reactions or (a)   them from occurring. Like catalysts, they themselves are not changed in the reaction.

Catalysts and inhibitors affect only the rate of a reaction. They do not change the (a)   of product produced.

Many reactions under certain conditions can occur in (a)   directions. These reactions are reversible.

A reversible reaction is one that can occur in both forward and reverse directions.
