How Chemical Reactions Work And There Components

Question 1

kinetics

Answer 1

The study of the rate of a reaction

Question 2

Reaction rate

Answer 2

How fast a reaction occurs

The change in the concentration of a reactant or product per unit time

Over the change in time

the gradient of the graph

Question 3

instantaneous rate of change

Answer 3

is the rate of change of a function at a point

Question 4

endothermic on potential energy diagram

Answer 4

reactants are lower than the products

Question 5

exothermic on potential energy diagram

Answer 5

products are lower than the reactant

Question 6

rate law

Answer 6

an experimentally determined process that can be used to predict the relationship between the rate of a reaction and the concentrations of reactants and products.

Question 7

collision theory

Answer 7

molecules must collide at the correct orientation. when collisions occur, bonds are broken and new bonds are formed

Question 8

activation energy

Answer 8

the minimum amount of energy required for a specific reaction to take place

Question 9

activated complex

Answer 9

temporary state between the reactants and products where colliding particles are at their highest energy

Question 10

catalyst

Answer 10

a compound that speeds up the rate of a reaction but is not used in the reaction

Question 11

enzyme

Answer 11

aspecial kinds of proteins and has the same function and nature as a catalyst
