collision theory and friends

Question 1

states that atoms or molecules must collide with enough energy in order to react

Answer 1

collision theory

Question 2

when molecules collide, a certain minimum energy called ________ is required for a reaction to occur

Answer 2

activation energy

Question 3

activation energy is suggested by him in the year 1888

Answer 3

Svante Arrhenius

Question 4

when did svante arrhenius suggested activation energy

Answer 4

1888

Question 5

is needed to break the bonds of the reactants to form new products or new substances

Answer 5

activation energy

Question 6

the speed or rate of chemical reactions is altered or changed by the following factors:

Answer 6

1. Particle size or surface area
2. Concentration
3. Temperature
4. Catalyst

Question 7

when solid reactants are present in small pieces, reaction rates can increase. The smaller pieces have a greater area, thus providing much greater contact among the reactants and effecting more collisions

Answer 7

particle size or surface area

Question 8

the measure of the number of particles of solute contained in each volume of solution

Answer 8

concentration

Question 9

another chemical change that happens all around use. Results in the deterioration of the metal

Answer 9

corrosion

Question 10

increasing the temperature increases the fate of reaction. therefore, heating allows more frequent collisions among particles. most frequent collisions will lead to sufficient energy that will provide necessary activation energy for the reaction to start

Answer 10

temperature

Question 11

the substance that alters the rate or speed of chemical reactions is called this. generally, this is used to speed up a chemical reaction

Answer 11

catalyst

Question 12

catalysts that slows down a reaction

Answer 12

inhibitors
