Front

Under the collision theory, the particles must collide with ____ and ____ for a reaction to occur.

Back

sufficient energy and correct orientation

Front

More collisions correspond to a:

Back

Faster reaction rate

Front

Which of the following is NOT a factor affecting reaction rate? Options: temperature, catalysts, particle size, polarity

Back

polarity

Front

Which factor increases only the effectiveness of collisions? Options: temperature, catalysts, concentration, particle size

Back

catalysts

Front

Reaction rate

Back

speed of reaction

Front

Why does decreasing the particle size increase the reaction rate?

Back

It increases the number of collisions

Front

To slow down a chemical reaction, what should you do?

Back

Place the reactants in an ice bath.

Front

Why does a higher temperature increase the rate of a reaction?

Back

it increases both the frequency and energy of particle collisions

Front

Which of the following increase the reaction rate? Options: less surface area, lower temperature, an inhibitor, increased concentration

Back

increased concentration
